Do I think Wall 2 Wall pulling is doable in every dungeon? Yes.

Do I think all tanks should learn how to do this? Yes.

Am I bored out of my mind when once every few months of daily expert roulettes they don't? Yes.

Am I more forgiving of new tanks in levelling roulettes / first timers? Yes.

Do I think it's my job to say anything more than "it's okay to pull more" or run around and pull mobs as a healer / dps? No.
