I generally favor PvE over PvP, but there is no way they are going to allow PvE to heal PvP (as it should be). It just doesn't work. Then you have people who can't be attacked affecting the battles of PvPers. You stay unflagged and keep healing the guys who are flagged while they PvP, that's just not right. Your group either needs to be all PvP, all PvE, or accepting that some cannot be healed by others (and I do agree the spell should go off, just not affect the PvPers). The reality is SotA is one of the most nicest games I've seen on the subject, just by allowing to to flag and unflag as many times as you like. That's as far as it should go.
