I don't run mentor roulettes anymore because of extremes.
Its hard to explain a fight when the sprout tank insta pulls, or when 6 of the people are German and ask you in German to explain it in German, because we all speak German on Light...
Most of these people are not ready for extremes, they can't tank swap, their DPS sucks.
Its easy to say that mentors are the problem, but if you're there to help, and nobody listens in an Extreme its gets very obnoxious after wiping on even Garuda Ex because they keep letting thevrocks get destroyed, because the Tank keeps turning the boss into the group
