Warlock/Barbarian Gestalt help

[Omegaxicor]

I'd rather not have an animal companion, it slows the game down for my teammates when I get two turns every round

I am going to go the Warlock//Spirit Shaman since it gets some nice features and it means I don't have to burn Xp to cast divine healing spells on myself when I go "Feyfire Warlock"
