I'd say the most unbalanced part about the class is how fast conqs (and bear shamens) can apply the physical torment effects. It's pretty funny. I always laugh when a feral growl crits and applies an instant 4 stacks. Trololol.
The double bubble isn't really the problem, although it is cheesy. It's the broken mechanics of picking up the flags.
And what wild said, there are players (like 2 besides me) that can play anyclass to its full potential..... except the necro. No one comes close to me
