Wintry

Notice of the Well, yes it was. It dropped from Khan/Barracuda two days in a row, but it also seems to have been fixed before the next morning.
Basically you could get one on tuesday and wednesday, but on thursday it stopped - miraculously without even a patch deployment during that morning's downtime.

As it currently stands it looks like I'll have a tier 4 on 5 different toons on the 15th - including a tank.

Copied from the in-game detailed info tab of Teleport Foe:

WARNING: Lots of text ahead.

The main thing that gets done plainly wrong on many STF runs in my experience seems to be the tower order and it often causes much more trouble than anything else at times. I'm not sure if it wasn't mentioned by the OP because they took the towers down in the right order or they didn't, but it was simply taken for granted as it so often by so many people. People are used the towers making trouble and Recluse being a bugger to an extent even without them, depending on the sort of team used.

Like I said, perhaps this wasn't an issue on the particular STF runs the OP started this topic about, but I'm gonna throw this out here anyway even if just because this is a good opportunity to bring it to the attention of all those people who still make STF a lot harder for themselves and their teams than it needs to be.

So... sorry for off-topicness, but I think this may be useful regardless.

In a distant past I used to start with red and leave blue altogether as it seemed sort of useless. I think it was endurance infusion at some point or another, but today I'm not even entirely certain of that anymore. What I do know for a fact is what they do today.
When I lead an STF I always take them down in the order blue, red, yellow and green. There is always someone trying to argue me on it and telling me to do red first, but that really is bad practice.
Red these days about doubles his damage (+105% iirc) and blue caps his recharge at +400% as well as giving him +30% tohit (those who still tell me to do red first also think the tohit is coming from yellow, but that's just defense). Not only does the recharge given by blue translate into a higher effective damage multiplier than he gets from red, it also means he attacks more often altogether and with that gets a chance to go through a def based tanker's def more often. Additionally the tohit is just annoying.
Bottom line: blue is the real killer nowadays.

On the only tanker I have myself each and every of these tower effects become extremely easy to perceive since it's a shield/dark tank. I'm largly def based and I self-heal with Siphon Life.
When I go into the fight (although it isn't a fight at first obviously, but you get the point...) I use 0 to 2 lucks (depending on if there's an emp with fort or other def buffs on team, etc...) to bring my def at or over 75%. Thank goodness AAO and Taunt are autohit making it generally easy to keep his aggro, but when he does start running he runs like a hyena on speed. When he sticks to me he attacks... like a hyena on speed as well. If for whatever reason I let my def drop substantially below 75% the hits start coming in at such speed an emp can almost never keep up anymore.
When blue explodes he pretty much goes into snail mode. He attacks slower and he moves slower - visibly slower. If you've never paid attention to it before, do so. Even if he doesn't run around but just stands there attacking the tank you will very easily be able to see he's a lot slower all of a sudden. It is however still a snail that packs a punch and the emp's heals are still all I have to rely on at this point.
Then when red goes down the damage drops again. This time - most obviously - not just the DPS he's putting on me, but the DPA as well. Many of his attacks that took me down to very low health before only still do half health at best. At this point it gets rather relaxing.
After yellow goes down I can finally hit him again and with that self-heal by means of using Siphon Life. The only thing not possible yet at that point (unless you can debuff heals in some way - I seem to recall there's an option, but I forget which it is.... Cold Domination I think?) - with just green left - is killing him due to the huge heals.

I've noticed many people still find themselves strengthened in their belief none of this is true because they still complete plenty STFs without even touching blue. This is entirely possible and it can even go smooth, but to be perfectly honest if you took down red, yellow and green before killing LR and it worked just fine that's not because blue doesn't do anything notable, that's just because you happened to have a team that could've taken down LR leaving both blue and red intact as well. It's all in the team you've got - that makes all the difference.

If anyone reading this knows of himself he's one of those who thinks I'm telling fairytales I'd advise you to bring a Power Analyzer MkIII temp on your next STF run and scan LR before you start killing towers.

TLDR; blue, red, yellow, green.

Is this possible?
I mean, unlike LR on STF Reichs doesn't have tricky things like scenes directly copied from Arachnophobia or anything, but my concern is much more basic: considering Reichsman's resistances, his max HP, the resulting regen and - worst of all - the way he spams unstoppable I'm not sure if it would be possible for any one toon.
I just successfully completed a 'solo' MO Khan today, but I say 'solo' because I dualboxed that one with an ill/storm and an ill/rad. I've seen on that run first hand that even with all the rad debuffs and a freezing rain on him at all times he went down very, very, very slowly (the TF in its entirety took 2:57:50 to complete) . That was with debuffs and psi damage from two toons, making me wonder if 1 toon could put out enough of eith... no, both preferably, to do it.

Has anyone ever tried this?
Could something sonic perhaps do it? Maybe cold/sonic? (That would be awesome, since I'm in the process of making one.)

If it's possible, I'm gonna have to give that a whirl as well.

Edit: Before someone says: Yes, I realize cold/sonic wouldn't be a troller. I posted this here because I've only really done these kind of challenges with trollers so far so that's what I have experience with when it comes to the matter. I am, however, open to any suggestions if people were to deem another AT more fit for the job.
