Marauder Tanking (not Warrior) at endgame?

[kasei]

Defiance and everything that comes with it - extra HP, crit/healing bonus, Inner Beast, enmity bonus.

You can't equip AF armour.

You can't equip relic.

It really won't be viable sadly.

I was offsetting Defiance's buff's with other skills, and without the damage debuff from Defiance you can still generate plenty of enmity. But damn, it all comes down to gear again, so much for that idea.
