What am I doing wrong? (WHM)

[Kyomih]

It's funny that with some groups I'm not even half of my mana at the end of a boss and with others I'm dead oom.
Not even talking about a bard here just the difference.

First boss there isn't that heavy on your mana, though if this happens it will be difficult.

- Damage to low to blow up the adds in time
- Tank not picking up the adds when damage is low
- Tank not popping his cooldowns at the right time
- DD taking red circles

Bard in group?
It also depends a lot on the dps output of course..
