Guess what happens if there are 2-3 more healers next to you? Something that's starting to happen more often these days. In fact I just did a Voidstar with 4 trooper healers and one sorc on my team, it was sad.
I'm not arguing with that, a healer shouldn't die one vs one against a DPS, but he should be forced to go on full defensive without outside help, until he's resources are depleated.
I play a sinper too, and vs several healers there's literally nothing I can do, I can hit hard but their health just goes up before I can shoot again.
Funny how that works. As DPS need teaming up and teamwork, even a comm chat, to deal properly with healers. As a healer you don't need that to heal, when you are backed up by two or more other healers.
The point is, healing is fine as long as there aren't too many healers around, like the OP says.
