I hate this dps-centric meta. It's only bred toxicity in every part of the community, it seems. And like every meta, how the top 1% plays bleeds into all other levels of play. Unless your pushing the limits of difficulty in this game (New raid tier and speed farming), the difference between being in tank stance 80% of the time or 20% of the time probably saves minutes at absolute best if the DPS is good and doing it's Job. I dunno, if the tank is good period, then time in tank stance won't change much for the overwhelming vast majority of play.
