Aggressive Protective. Now that's a real Celt.
High Charisma with Leadership should be fine. The minions will likely be more spread out as running camps and towns and working, etc, rather than used in combat, as I'd rather not try large scale encounters right away. Cohort is fine though.
And no, I didn't list my house rules deliberately. I've already got a campaign or two running with them in it, and I'll try a slightly more standard one this time out. However, should anyone wish to try a class, or class-affecting houserule, they're free to do so.
