Show me the screenshots of you super tanking the AAs in Divine Might II on (D-VD) while your alliance pulls them off you and I'll change my mind and say RUN can tank as well as a PLD. With an Ergon or without, either will do.

Or if you'd like, send me the pics of you super tanking Gramk-Droog and his adds on a pull at level 135+ Incursion.

I'm betting you'll do fine, right up until Battuta runs out... then...
