i played for about 20 hours and as a healer i can tell you, its exactly the same as any healer i have played in any pvp MMO. there are guys that rant bc "NO HEELZ!" and there are guys that just play.
The order warbands i have fought in tier 1 are way better at ganking the healer first than we destro seem to be though. rarely do i get to just heal. mainly i have to heal, heal, heal, then shield and hot myself and run around like a headless chicken bc i am being focused. there are no heals happening then. Sometimes i would have a friendly tank shielding me but by being close to the tank i just get focused faster.
Also Pug warbands tend to not have a healer for each group, so i end up click healing all over the place, and trust me there is always more than one friendly player getting hit at once.
The quickest way to die as a healer, is to focus heal a single guy getting whaled on. All of the guys whaling on him will quickly focus on YOU when they notice him getting big heals. This is also what most people expect you to do in thier Pug warband too, so this causes lots of friction.
I then tried staying way back and healing out of line of sight of the enemy. but that results in everybody getting out of MY line of sight and, guess what? no heals. Then there's the guy demanding a rez when we are being spawn camped, and he's 50 meters from the rally flag... There's also the the guy who passed me 10 gold in the middle of a crazy fight to help me out


All of this is just to say, try to be a little more patient with us level 10 - 12 healers. we did not LET you die on purpose. we were either in the middle of healing someone else or more likely running for our lives. or frantically trying to click on you to target a heal when your hp bar is dropping like a flaming zeppelin.
Hope to see you out there.
