The only real answer I can think of is tome of the wilds.
A talent would in my opinion not be sufficient
And a PvP talent even less so.
But even these both would be much better than the current forced, and force-fed to the player!, overstuffed turkey form.
It is a disgrace to all Balance druids, who function as the keepers of the natural order, not some flightless poultry moaning about while being chased by a hunter.
The current iteration is a clown show, plain and simple. Its a fucking joke, and a very bad one at that.
Its okay if you cosmetically make it a clown show SOMETIMES for shits and giggles, but to force it on serious players is a shame.
