Disturbing trend with tanks

[Almalexia]

I'm also unsure why AV is considered a toxic zone

Probably the poison gas.

Anyway, AV gets a bad rap because it has a bunch of annoying mobs and boss mechanics that are all concentrated in a single dungeon. Locksmith requires everyone to participate, Coincounter is baby's first no-AoE-marker boss, and Mistress combines all the personal responsibility of boss 1 with the positional awareness of boss 2.

All the trash mobs come in groups - big groups - and everybody is too lazy, timid or ignorant to AoE.
