In my opinion, you killed PvP with this patch
Yes, nerfing Evasive Arcana did gut ele bunkers pretty bad.
But it nerfed elementalist as a whole as well.
Evasive Arcana is now pretty bad and not worthy of grandmaster status. The worst thing is that all ele builds pretty much need 20 arcana minimum because traits suck.
Probably at least 50% of elementalists used EA because ele sucks for everyting else.
Whats more dodging into fields was fun and made for an engaging playstyle.
Eles suck at so many things that they are shoehorned into a couple builds, they looked at the strongest build and nerfed that and everything else in the process.
Besides ele bunker no one ever says ele is overpowered (its usually underpowered and people have no trouble killing us).
So what did Anet do? Nerfed ele as a whole. Sure staff has a lot of fields but now few blast finishers and the sad part is that blast finishers are needed to prevent you from dieing using a staff.
Most people agreed EA was overpowered. Putting it on a global 10 sec timer would have been a much better fix.
