Guild Wars 2

i will keep this simple reason druid is not used in WvW is because it condition clear is good enough enough compare to ele or rev well it healing still output exact same number of a ele or rev.

so my suggestion would be to buff druid. condition clear by adding remove 1 condition from 10 allies when casting Comsic Ray.

just to give a little math behind it so you guys understand difference in con clearing.

over course of a minute.
ele can remove up to. 54 con x 5 allie = 270 condition over course of a minute
rev can remove up to 60 con x 5 allies = 300 condition over course of a minute
Druid can remove up to 45 con x 5 allies = 225 condition over course of a minute

Are you including blasting light fields?

i am including what class can do by itself not runes / food or blast finsher. guess if i did rev would be slightly higher in though numbers.
