As you can see in my thread here BM is suffering from having the among the fewest talents in the game and one of the most expensive trees in the game.
Not only that, BM has to talent into things like Multi-shot AND Beast Cleave while these talents are also more expensive than average.
BM needs a talent overhaul to reduce the cost and increase the number of talents in the tree. BM also needs an actual cooldown because 1) BW is almost always active 2) AotW feels and performs lackluster
