When should I drop tank stance?

[Kabooa]

When i'm against bosses, I start on dps stance and ask people to use enmty control actions, they don't and I end up using enmity combos more than I should.
Be aware that people aren't used to tanks in dps stance. I was kicked from a group once even though we got to the last boss without a single casuality, they just couldn't accept how I wanted to play and decided to kick me few steps away from the last boss. I guess the extra healing is too much for some people.

And once Diversion goes out, I'm going to pass you. Solo tank threat generation outside tank stance is ass, and you save yourself a huge headache by just doing one single threat combo in Tank stance before dropping it, because it's like the equivalent of doing 16k DPS worth of threat. But no, sure, do about 50 more DPS over the course of the fight just so you can tell everyone else to "use their enmity control actions".
