I am EU so i cant post here, but i read all of this forum that Cyous made on us forums, its a really nice discussion about how we can change our class for the better and make it enjoyable still.

But yeah problem is that if we make a forum anywhere to try to discuss class mechanics and changes you will get pages of disagreements and arguments and people posting useless stuff, unless its moderated harshly where only idea discussions are kept.
Btw is the build on ptr atm the one with SS proc rate nerf on multi target? I logged last night and it really didnt feel too bad on 4 targets.
