Is MRD good enough ?

[Kal-El]

MRD is just fine, its meant to be a offtank later on to grab adds quickly. Just mark which mobs you want sleep on and turn the others away from it so overpower doesnt wake em up

No it's not meant to be an off tank later on.

I don't know if people are basing this off old data but WAR/MRD has been buffed while PLD has been nerfed to make them on par.

I can tank anything a PLD can easily.
