I did the first Adventure as a healer last night. I'll just say that healing in this game is NOTHING like anything I've played before. MMO healing has always basically come down to playing whack-a-mole with group/raid frames. Wildstar has you running around like crazy trying to line up your telegraphs to make your heals as efficient as possible. I will admit that it took me a while to even begin to get the hang of it, and I have a long history of raid healing. I also think healing is going to rely a lot on your party members playing smart and staying within your telegraphs when they need to. The actual healer can only do so much in that regard.
