In my personal opinion the heal skill should get tweaked a little bit. The one second delay just feels too much for me.
my 2 cents on the Revenant PvE wise generally : Props to ArenaNet for improving the profession, for reals, awesome that they react to our feedback, but to be honest, anytime I do PvE content with the Revenant and switch to another profession it feels so much better just because of the DPS alone. I know it’s all new n stuff but it still does not feel as viable as the other professions.
