I had played with a crit rage archer ages ago and he's at level 18 right now. I'm thinking of pushing him to 20 for the free epic TR heart just in case.
No point in running him with 14 barb levels though, so I'll drop the LR 20 on him and rebuild him as needed. Stuck with Elf for now. First life character.
Really, I think I've got the basics, but what people do with enhancements on these builds I'm not sure. (Odds are, I'd TR him through ranger a few times before messing with epic.)
