Tank Stances.

[SpookyGhost]

I hate this dps-centric meta.[...]

The faster you push phases/kill the boss, the less abilities you have to deal with, the higher chance you have of clearing the fight. If it's casual content then it's w/e, you'll kill it regardless, but if it's a raid then you should be contributing as much as you can for the good of the team. If the team decides you're better off in tank stance 80% of the time, then that's fine... but generally that's not the case, so it's useful to learn how to stay out of tank stance optimally without getting yourself murdered.
