Okay, I'm a newbie and I have four ascended characters. The healer is really the class I preffer in PvE. But when comes the time to help my guild in Guild Battles or simply doing PvP in arenas, I simply suck: I just cannot stay alive!

I know monks are the primary target... but there is no way I can even start enjoying the PvP part of this game if I'm always the first one down only after 30 seconds of serious pounding!!
I tried many combo: Mo/Me, Mo/W, Mo/E... none of them seems to survive very long in PvP. So, is there a way to make this game playable/enjoyable as a healer or do I have to change my vocation?
Thanks in advance
