The cone was perfectly fine as it was. In fact it was arguably the best tank aoe due to range and the reposition dance encouraging mobs to keep clustering in large pulls.

I can see an argument for making selecting a target optional, as long as selecting a target and casting still oriented your character towards the targeted mob.

If warrior aoe now feels as terrible as the other three tanks I see no reason to continue playing it in dungeons. Maybe then my complaints will have weight.
