I love it and I rock hard, of course it helps that I have an uber partner(s) in crime. 3 of the classes have healing trees, my main is Jedi Consular/Sith Inquisitor and it's nonstop action. Healing, bubbles (not LOTRO style), combined with CC and damage dealing when I'm not busy spamming heals.
You can also be a healy pewpewer. I haven't much experience playing Smuggler/Imperial Agent, but Trooper/Bounty Hunter was pretty fun as a healer. Entertaining shooting at things to heal them.
my 50 assassin, 37 Imp Sniper, and 36 BH Merc are great fun. Of course I am loving republic side too lol
