There are some very interesting prcs in combining classes that I think deserve more play, especially between two homebrew classes. I made one that combines the owthro evolutionist and swarmlord to that allowed all feature lists and point pools to be combined, and I think the evolutionist has a lot of theurge content. I find it very fun.
Also I might make it a project to rewrite all the material for owthro ozodrin for the remix, but that's not relevant to anything.
