Possible beastmaster class
Beastmaster (BST): Weapon: one-handed axes/shields Main Function: Tank/DPS
BST can call upon Familiars (animal spirits) to fight for them. Each familiar should have its own skill sets that bring new abilities/functions to the party. The one difference between BST and SMN could be the way the BST interacts with its familiars. BST could possibly be shamanic-like and have the ability called "Fusion". Upon activation the summoned familiar is absorbed into the BST (thus leaving the battlefield) giving the BST different affects. This fusion is permanent until deactivated.

Just some ideas (balancing wasn't taken into account too heavily!)
