Guild Wars 2

I see more people complaining that making positive comments about the way the thief is atm, so please Anet listen to your costumers. Why not improve other professions instead of nerf the ones that are already good and fun to use. So when the other professions get OP u have to imprvoe even more the thief and so…. u will be getting every profession better and better with the time. I think that is called Progress

Improve not nerf please !!!

(I post here because most of the people read this forum, my main lenguage is not English so i hope u understand me xD)

Because nerfs can be improvements.
Unless you mean buffing when you say improvements, in which case, only buffing and not nerfing leads to ridiculous power creep, which causes balance between professions to become even more tenuous, and trivializes PvE content even further, which would require buffs to PvE enemies and blah blah blah. In order to reduce the effectiveness of one thing you need to buff everything else.
Or, instead of that, you nerf the one thing that’s better than everything else.

This is about balance theory, not thief specifically, don’t get your kittens in a bunch, thief forums. Even though bunches of kittens are awesome.
