My main will be a DPS or tank SI Assassin (lol@too many tanks) but my Republic character will likely be a healer so I can heal as my bro DPS's or tanks. Think he wants to play a gunslinger. I healed in WoW with a druid, and I currently enjoy healing on my Chloromancer in Rift. In the end, what I end up doing will depend on what my brother and sister decide. If there is no tanking among the three of us then I will tank on one of my toons (Assassin or Vanguard). If not, then healing will be on Republic side only (Sage or Commando). As someone who likes DPS classes, I find healing to be a nice change of pace. As long as I have the option to go back to a DPS role from tanking or healing I will do all 3 roles and strive to be awesome at them.
