Judging from Raid / Dungeon content so far and comparing with other tanks aswell as reading on multiple forums it would seem that Warrior AoE Threat is somewhat low.
Even with the homogenization of tanks where most of our abilities equal those if other tanks it feels as if we're still behind.
One proposition would be to remove the lackluster 2-Target cleave and give all three warrior specs whirlwind. Or give back the MoP beta 5 target Cleave.
Also wtb the old Vengance transferring Vigilance, theres just no way to pick up stuff from a Vengance stacked Tank.
I know this only concerns 5 mans and Trash-Pulls but for me at least who is tanking against a feral druid it would be a welcomed change.
