Guild Wars 2

Well hello guys i have been reading all the happiness and rage about the changes of April Patch and i have a question about stats

They say that they will nerf Zerk stats right? soo now which set will be the most dmg dealer in the game? I just want to know for my warrior that is my Main (its my only 80)

And my second question is where i can see all those changes that they ll do to the game?
I heard about a youtube chanel that make videos about what is going to change in the game

Well thats all , Sorry for the bad english

Thnks

bersek gear will still do the most dmg, 10% less dmg won´t drive me and many others away from being full bersek

i can recomend you dulfy.net to check all the changes and guides if needed
