How does SE justify these ten min enrages, but doesnt let anyone know their dps

[Reynhart]

This forum allows 1000 characters for a single post, I had to downgrade mine from 1950 to 1000 characters and it's lost the charm.

You can edit your post to bypass that (unless you're on a phone, I think)

The point is they don't die. They lose dps and we wipe due to enrage timer.

They don't need to die. If you see everybody run away from a player-targeted AoE, you can suggest that only the person targeted should move away. Or, like someone above said, if you need to spread, suggesting that ranged DPS move further so that close ranged DPS can stay on the boss.
