I think that this is fairly balanced, but with the level 1 talent Blooming Treant, the other talents that spawn Treants, and Serenity, your team gets an insane amount of healing, essentially restoring everybody to full health, and it's even more insane if the Regrowth stacks. If you get the level 13 talent Harmony, the healing is even crazier. In addition, all of the Treants will give insane damage output as well, so long as you land Entangling Roots on an enemy.

Very interesting, but with the level 20 talent Hastened Return, it says when they die while under the effects of Guardian Angel. With Guardian Angel, it makes them invulnerable and then they get a shield. You cannot die while invulnerable, and once the shield breaks they are no longer under the effect of it. So how does this talent work?

I feel that the cooldown reduction on Ferocious Bite should be lowered to 2 seconds, as if you apply Thrash, Rip, and Swipe, and then consume them, it will deal tons of damage and then have a 1 second cooldown. In addition, does the level 1 talent Predator also apply to consuming the effect with Ferocious Bite? If it does not, I feel it should, as that would increase damage potential.
