Going Medic Operative isn't that bad. I've a 40 medic/operative and I handle things just fine. It's not like it's impossible to do a medic right. It just comes down to energy management and understanding how the heals work off each other. And once you get surgical probe it becomes fairly simple to keep people alive. It's not that complicated once you get the hang of TA and how to trigger it. It's about energy management, energy management, energy management. Also, be prepared not to be dealing damage during FPs or Heroics. you let others do that and you keep them alive. It's fun, actually, at least for me.
