This is not to debate on how "cool" or "uncool" Rhinos are, it's simply about the talent they have: Stampede
Stampede: Your rhino slams into a nearby enemy causing it to take 30% additional damage from bleed effects for 30 sec.
1.To get a Rhino you must be a Beast Master
2.Being a Beast Master means that you do not have any bleed effects.
The only argument you could make for this would be bringing it into a group with say.. a warrior or rogue, But If your bringing a pet with the intention of helping your group i'm sure the corehound, shale spider, or delvisaur/wolf would all prove more useful?
I could be wrong about this, anyone see any reason why the Rhino has this ability?
