Well, since this seems to be a thread about wistful thinking for ninjas... Here's my own proposals...

All ninja-
Powers: All of them need KB protection. Since they're mostly melee oriented pets, lacking KB protection can be a big problem, and none of the secondaries give KB protection. Possibly immobilize to.
Furthermore, their need a massive defense buff, by level fifty all ninja have their defense increased by... About 1.9%, this does not even bring Genin out of the woeful single digits. Worst of all, other Pets that use Defense such as the Enforcers of the Thugs MMs and Protector bots grant higher defense buffs out of the box than the genin do at level fifty. By the time you get your second enforcer or protector bot who stacks this defense buff, they grant more defense than your jounin have at level fifty. Oh, and they can be slotted for defense buffs, making their ally/self defense buffing EVEN STRONGER as the buff's defense boost also increases with the MM's level. Something SERIOUSLY needs to be done.

Genin-
Art: Genin lost their equip graphics change when it was decided genin should not have archery, those losing a quiver they got. This was pretty sad since I tend to look forward to how a minion changes appearance with each upgrade, and thugs, right now, are the most visually impressive. Plus, I think with the Samurai vet reward costume pieces and martial arts booster, they could stand to look much better.
Powers: I will say right now that I never liked exploding Shuriken, perhaps if it could be changed into a long ranged cone of a handful of Shuriken?

Jounin-
Powers: The jounin could be compared to the Zombies Grave Knights... Except Grave Knights have a ranged attack out of the box. In the end this isn't such a big deal since by the time you get your first jounin, you'd have had your first upgrade for six levels, but it Caltrops does not strike me as a decent ranged attack or much in the way of area denial or mitigation.
Edit: Another problem with the wrist crossbow (besides it kind of sticking out an awful lot on the jounin's costume) is that it forces redraw, one possible solution might be to replace this poison dart with either similar animation of the origin temp powers (which do not cause redraw) or possibly giving them the Syndicate Sword Master's ranged sword attack.
Art: Okay, not a pressing issue as the genin, but like the genin, I think their appearence could stand for an upgrade with the help of the Samurai Vet reward and MA booster pieces, maybe have one of their upgrades involve getting a sleeveless baggy top with the irezumi/yakuza tattoos like the Tsoo enforcers have. I think this might make them look a bit more interesting as Sam puts it.

Oni-
Powers:

Personally, I think the whole ninja set needs to be looked at and rebalanced, namely the single digit defenses (seriously!) and I think costumes should be looked at too, especially since the genin update of dropping the archery, they've lost their first costume upgrade. I do agree that thee oni does seem to be an odd man out from the rest of the group, even weirder is that he's supposed to be a warrior of "WIND and fire" but has no wind related powers.
anyway though, while I don't entirely agree with this, I think one possible alternative could be to get a Kunoichi instead of another jounin.
The Kunoichi could use a mix of Illusion controls, poison, and Kin melee with the full debuffs.
... Of course, you're forgetting something important.

Cottage rule

DM, that was awesome.
Dante, that was Epic!
RedTornado, that was GODLY.

I'll sign this!
ka-/sign!

Like I keep saying Sam, I think there's a compromise.
I think the dead ends just need to be more interesting.
Like in a tech lab, I'd love if that dead end had something to it, like those incomplete portal rooms, or like a chamber filled with pods and such. (Though sometimes that could lead to ALOT of questions about WHY something like that would be in a computer hardware development firm...)
And I do like the vastness of Paragon, but the empty vastness does seem a little sad. So instead of just block after block of generic building, wouldn't it be cool if Skyway city had a Performing Arts theater, an art museum, or having it's high ways actually sprawl out and lead to other zones?
Of what about the war walls being painted with murals, defiled with graffiti, or even people starting to simply build into them?

well, kind of.
In RP we sometimes do.
A particularly funny incident was my main Rogue: Redcoat was winding down a bit of teamage with his wife, she was telling him how everyone thought he was a big dog these days and he insisted he wasn't.
Cue no less than SEVEN passing NPCs all making some comment about him and something he did recently in some mission or another.
Then cue him facepalming and wondering if these people are looking him up on google or wikipedia.

As a random note about morality in Praetoria, I would like to point out that Cole wasn't the first to bring shades of moral gray to the world, you might say their "morality evolved different than ours."
The America mentioned by the hobo is not our America, it is not CoX-Verse's America, it is an America that Elected General MacArthur for President. It is an America that swore a man into office who dropped nuclear bombs on on the borders of North and South Korea during the Korean war, killing thousands of our own people and the people America was supposed to be protecting as well as possibly causing nuclear fallout that likely devastated Asia well before Hamidon came about. Indeed, it truly was a darker America that felt justified to drop nuclear weapons on itself and kill millions of American citizens with a weapon that caused enormous collateral damage, and by that point had proven ineffective against against the advance of the swarm.
It was not any America we knew. The world of Praetoria had changed long before Cole even gained power with Stephen Richter and killed him... It is... a Grim Dark future...

To the OP, you need to remember that as nice as those words were: Marcus Cole, in any incarnation, seems very very good at speeches on the spot. I'm sure he could have convinced you with a speech that killing your own family would be for the good of Praetoria.

Also: You went Powers Route, you're a villain, plain and simple.

To the one wishing they could be a StormTrooper, not the best idea: Your inherent power would be "Imperial Stormtrooper Marksmanship Academy Graduation" which would be a permanent -100000% ToHit and Accuracy debuff to self and all teammates.

This is kind of a small problem with Praetoria, the devs wanted to see it all in shades of Grey, but everyone of significant power in the established government (Manchard the exception) is pretty ruthless and evil (The Praetors, Cole, Etc.), not helped when they've explicitly established that the old Praet arcs ARE Still canon, this is just moving along on the timescale with the Praetorians attempting ANOTHER invasion of our world.
Oh, and there's the whole "brainwash the citizens" thing.

It was fun when I duoed with with a blaster on my Will/DB tank.
I was jerking Protean around by spamming taunt, well outside of his siphon radius while the blaster kept shooting at him.
If our character models had fingers, I know my tank would have been flipping protean the middle.
