1. As medicine u will use more keybinds than dps but that is because you have your dps binds and your healing binds, I use both evenly
2.Stealth is pretty much worthless once the game gets started. Combat never seems to break as a healer, so actually using your out of combat regen is not an option 80% of the time. I've even used cloaking screen just to break combat before.
3.Healing as a operative almost seems prefect in pvp to me. I been healing spec since lv 10 and at 10.3% exp and don't have a problem healing at all hit 300k on a fairly normal basis
4. Our energy probes seem to be up at the perfect time every time, never really have energy problem when I'm grouped with friends since stuff actually dies
5. I think our cc is for getting away from people flash bang has a little range on it, and sever is perfect for kiting melee classes.
6. Yeah but that is all pugs in mmos really
I think operative healing is perfect in pvp, never had a problem with. My only issue is in pve something seems horribly wrong to me. Our hots do **** for heals and getting more than 1 person up kills our energy bar quickly. I hate that our 2 most important heals are semi proc based
