There was that too. But if that was all they could do it'd be good but not CoDzilla worthy. Being able to do that and summon 1d4+1 animal helpers, send your animal companion to flank, buff yourself, and more.Not only that, but they gained the animal stats. So if you choose a dire bear, you sudenly gain +16 to STR and +8 CON. That makes the balance jump off the window, because a Barbarian gains +4 STR and CON with rage, and the druid can cast firestorm, call lightning, barkskin and regeneration.
But all of that is fairly iconic to the druid.
Late 3e and Pathfinder showed you could keep the feel of wildshaping without making it too broken.
