Doesn't it seem like 10 minutes is a ridiculously long cd for Challenging Roar (as well as War's Channeling Shout)? It's useless in pvp so it wouldn't cause imbalance if reduced to, say, 2 minutes. Wouldn't you think that a big mean ol' dire bear could manage to produce a decent roar more than once every ten minutes???
Think it would do any good for us to start lobbying BLiz for a reduction?
