If you go as GLD or MRD you can pull Blood for Blood, Raging strikes and stuff cross class.
Then since you're doing so much damage, and still get your enmity combo and things it's possible to keep hate.

Plus if you're doing trial roulette, for example, you never really need two tanks. So bring the damage! I'm always amazed at how few tanks I run into with strength accessories in the easy/highly overgeared content.
