I would really like to see TA become a set that other players can fathom WHY anyone would bother playing it. It's a painfully laborious set to solo with, and on teams its debuffs are pretty much outclassed by scrappers and brutes who are also killing mobs 70x faster than my TA.
That said, I don't know that I would want to see the set "overhauled" per se. I like that it is kind of a jack-of-all-trades, master-of-none set. If they could tweak the set to be more effective at the things it does, I would be a happy camper.
Maybe that would come in the form of a progressive AoE Build Up effect tied to animation/cast time of powers in the tree?
Or maybe they could slap some ridiculous procs/autohits into the tree, like say, Flash Arrow still does -ToHit, but it also floors Defense/Resistance in the AoE for three pulses of 3s spread over 10s?
Or maybe give the various powers complementary effects that stack, like say if the target is hit by Glue Arrow or Ice Arrow, then debuffs from DA or PGA are doubled in magnitude or duration, and so on.
I dunno, I just want to T4 my Ice/TA wothout clawing my eyes out.
