One of the biggest hunter problems was the defence against lot of enemies.Especially in pvp id 2 or more ppl are after you ,you were dead and there was nothing to do about it.
Warriors and priests have aoe fear,mage pallas bubble,restos habe heals,rogues vanish sprint etc.BUT hunters nothing.
With wotlk and rhinos something is change.
"stampede"
Your rhino slams nearby enemies within 10 yards, causing [rank] damage and knocking them back 15 yards.
Ole!
