Is threat # an indicator of damage output?

[Kevee]

If a monk and dragoon dont pop any buffs and dont use any threat drops, spending 100% up time on a boss, then yes the threat meter would be a remotely decent way of telling damage.

"not all actions were tested."

They tested the tank buffs, and actions casted on others.

Nothing, at all, mentions DPS cooldowns.

Quelling strikes does not "drop" enmity, so if you are already getting agro its too late. What it does is limit the hate you gain on your next strikes. So you have to use it before you NEED it.

Needing does not necessitate an immediate or reactionary use. If you know you'll pull aggro, before the fight starts, you know you need to use Quelling Strikes.
