Wait what...? Yes, we were OP as shit beginning of Cataclysm. No one would ever deny that unless they're delusional. No, it wasn't because of our mobility. If you don't believe that to be true then just look at how retarded the 4.1 juggernaut change was to where throwdown dr'd with charge stun. Do you know why it was retarded? Because our only method to reliably get to our target failed to hold our target in place. So instead we got a lower duration stun but A REMOVAL OF FUCKING INTERCEPT. So we in the end we were worse off in mobility than we were a patch before where it was already established that our mobility was overall terrible.
You site our viability in competitive PvP. Then please, for the love of god, stop ignoring the facts and see that warrior representation has plummeted. We used to be powerhouses so we could deal damage in the super small windows of burst we'd have. That burst was reduced overall. And now we can clearly see that MOBILITY was the problem to begin with.
