People who can't do AOE rotations in 70+ Content

[SnowVix]

the only place where this is actually valid is Alzadaals, where those mob spawners can be STed so they don't spawn anything, anywhere else you are a massive detriment by using ST in AOE
going from thousands of potency every GCD on a big pull to like 300 potency a GCD is not worth the tank taking damage from 1 less mob

also the Roilers in Amaurot, since until they die, the healer will have debuffed healing and that could also pose issues.
