Pretty annoying and overpowered. Don't think Bioware thought this one through. A shadow or sin can be almost dead, pop their combat stealth, cc you while in stealth, then come out of stealth and use their out of combat heal to heal to full just about. Awesomeness. I really really wish Bioware would do something about it. Not to mention they have 4 CC abilities.
I bet you are a VG/PT that duno to play. Healing out of combat is skill.
