Alright, sounds wonky enough to catch my interest
I was thinking of going with a druid, not crazy half breed combination things, except maybe half-elf, depending on how he would be built, but even that is unlikely.
I cannot say for sure how he will be built, it would be easier to wait until I know the rest of the party to decide what we would need. I would like to build him as a Druid/Barbarian that essentially uses spells to put all sorts of crazy effects on his weapon and buff himself and then go rage on things.
Either that or have him be a grappler focused character using spells and wildshape to increase his grappling. Or just have him go pure spellcasting, which I can build either a buff focuse or damage focus. Pretty much I can make him focus on just about anything, which is one of the reasons I love the druid class.
That's the build combat-wise. Character wise I have a couple different ideas mulling around, though they are all fairly straightforward and simple, I prefer to have my characters develop during the course of play rather than have most everything already set pretty firm due to an intricate backstory. But I do love story driven games, for me D&D is more about the story and the RPing than the dungeon crawl, level grinding monster mash some games focus on.
