I don't expect sprouts to pull big in low-level dungeons. They're still learning the game. I try to offer advice, but if I wanted the dungeon tanked my way that badly, I'd queue as tank and do it myself.

By Stormblood dungeons, though, I expect players to know how much they can handle and go for it.

Except for Bardam's Mettle. That one's still fairly brutal.
