For me Karma Mirror is pretty good spell.

It is nice to stop dot's and if you add regen self you are pretty good.

It is pretty nasty to put when marks pew pew's you and if he uses recharged well it ticks twice on him.

If used properly and you have enough HP a low health barb can suicide in it - i have seen it several times.

As a plus it have less shiny animation compared to Force Armor.

Lastly it is not bound to gear and resists.

But again no matter how buffed and geared you are if there is no teamplay you are dead meat.
