If you're bored of standing and spam healing a tank, then go half spec heals/dps and PvP. Granted, my MMO experience is limited mainly to WoW, SWTOR, and various F2Ps, it seems to me that most PvE healing comes down to 4 buttons, moving out of fire, and sometimes stacking.
Personally, I don't see Operative healing ever getting boring. Who doesn't want an army of healing droids orbiting them at all times?
