the pen and paper PvP is strong in here. sadly the OP ignored all facts possible and failed to understand why shield > 2h for 83,33% of the tanks ingame (#memathskillsonpointtoo).
the math done in the OT is 100% irrelevant for actual PvP situations and i'd consider this whole thread as a waste of time since all class related benefits for both SnB/2H and a lot more is left behind. but that's just me
I take it the one tank you consider viable is the sm? Even in orvr, Bretin? WODS goes a long way to making up for it but you don't think it needs that block chance?
