There is something wrong with having an army of spamming pets. I like the idea of one of each type, except for fairies and pixies.
Swallow would be the first line of defense (aggrivates and then evades)
Bear would be the second line of defense (tries to block)
Hawks would be the third line of defense (triest to block)
Bees would not defend, but they would do flare damage like a lshield
Fairies and Pixies would stand there and watch the druid die.
Pet levels might need adjusting, but this would be a good start to balance.
