Idea: Dual primary or dual secondary
Because Kinetics/Cold Domination, or Robotics/Thugs, TOTALLY wouldn't be overpowered. <<
It's funny to think about but it shouldn't be in suggestions. The balance issues would be catastrophic.

overpowered in some, underpowered in others. A tank whose only attacks are jump kick, flurry, and air superiority is probably gonna have a hard time soloing anything higher level than themselves. I just think it would be fun, maybe as a vet reward. I think the inherant weaknesses that come with overspecializing would keep it from being much more than novelty. A broadsword/Martial arts scrapper, if it gets hit it dies. Bots/Thugs would be fun, until something thats not been debuffed did an aoe that scragged all of your unbuffed weenies and left you there without even a tier one knockback to help you run. There would be a couple combos that I'm sure would turn into farm builds and such, but really, doesnt that happen every time they make any kind of changes? Devs make changes, brilliant scheming players find a way to throw the balance of something waaaay off, the devs fix it, such is life in the MMO worlds.
/No
Imagine the gimping of trying to solo with Stone/Ice Armor? You'd have little to no damage output.
Coincidentally... Any/Any Controller Primary.
What about Stalkers? They RELY on their secondary's first power.

MM pets buff each other. Between Force Fields, Thug Leadership and regular Leadership, Bots/Thugs would have about 60% defence to everything.
Vet rewards would be rubbish. The vet rewards need to be something fun (eg reveal, costumes), not game changing.
And nobody should have their normal sets nerfed just because it's overpowered when someone who's been paying for 70 months uses it along side something it's not meant to be used with.
It's an awful idea.

Quad wielding triple arrows would be fun!
Stone Armour/Empathy.
Plant control/Fire Control
Hmm
A Forcefield/Kinetics Defender would be buffing heaven..
And the defender could spam that AoE thingy in Forcefields!
I've always wanted to play a toon who had 2 primary powers, or 2 secondary powers at the expense of the other.
Something like a Shield Defense/Fire Aura Tanker or Ice Control/Mind Control Troller, something extremely focused, more conceptual builds than anything. I've just always thought it would be fun.
What do you think, what combo would you make?
