Concerned with upcoming changes...
From what I’ve seen both ingame and on the forums, the majority of the thief-targeted complaints are about one or two certain thief builds that are very easy to play and can cause a lot of mayhem if used against players who.. do not know how to “counter” the build well (i.e. dodge).
ArenaNet has done an okay job thus far with balancing, and we’ll be seeing more balance changes come the large November 16th update. I think I may be more eager to see the balance changes than the actual event, hehe.
Bugs have been and will continue to be fixed, but fixing them does take time. This includes necromancer bugs, which have been more heavily targeted (for bug fixing) by devs than the other professions in at least a couple patches thus far.
While I know that they’re aware of condition builds doing poorly against environmental objects and enemies wherein it isn’t possible to stack conditions onto them, they have expressed that that issue is not an easy one to solve.
In regards to condition stacks – there has been a lot of out cry about it, much that I personally agree with, and surely they are aware of it, but I don’t recall seeing them post any official stance on the issue one way or another. Perhaps if they increase the max stacks (or maybe even change the way that stacks overlap) in PvE but not PvP…
