Tricky one, al vocations are different. Sure both mage classes seem to be similar but in actual gaming, especially at higher levels the roles they take are just way too apart from each other. In Team hunts a good Druid should be able to keep his dps while maintaining the knight alive, this takes caring from part of the player; Sorceres on the other hand are there to burst down anything with their spells.
In my opinion not everyone is made to be a druid and not everyone to be a sorcerer. Taking myself as an example, i'm a good druid but when i play sorcerer i feel like i fall short on damage compared to when i'm on my ed, Same goes to a friend that's amazing at taking down waves with his spell rotations, he knows where to stand and how to move but when he tries to go druid, it ends up in all out mess.
Play the vocation you feel suits your gaming style better... You seem to like sorcerer way more than druids and base your doubts in the fact that "druids are better atm" something i don't agree on.
