Indeed. Not to berate the OP personally, but I find it highly amusing that someone isn't prepared to deal with a little incoming damage in a thread about "tanking"...
I think the problem stems from misconceptions about what "tanking" means. A lot of people seem to think it means "I flyz da croozer and shootz da beamzorz!" When you disabuse them of that notion, even non-maliciously, its like you are the big, bad wolf blowing down their cardboard house.
You gotta love the persistent escort tac captain perception that the escort does the most damage and everyone else's role is to support them. It is the duty of every player in a group to try to keep themselves alive. A tank can just as easily mean staying alive and maintaining damage on a heavy target while escorts struggle with the concept of strafing as it does to attempt to attract and sustain all damage for the benefit of glass cannons in need of a Caitan's 9 lives. While attracting damage has it's uses, it forces you into a specialized role that will impact your adaptability and potentially, your teams capacity to achieve an objective.
I've done enough experimenting to say with confidence that there is no one correct strategy in STO. The combat mechanics are too dynamic, allowing for players to mix different different strategies and play styles and even favoring those players that can adapt to situations and create new strategies mid game.
