Most listeners don't give a shit about 'party class balance' (whatever the fuck that means) or 'actual combat' (doesn't Amarth shoving a broadsword between a dudes shoulder blades qualify as combat?). It's a comedy podcast. I'm sure there are podcasts out there where unfunny motherfuckers sit around and roleplay the shit out of D&D, but this is not that podcast. I'm NOT a D&D player and I just listened to every episode, and thoroughly enjoyed it.
That being said, Amarth DID fuck up the disguise. I know Blackee has a 19 charisma or whatever, but I don't think even he can pull off a disguise that has a gaping blood-soaked hole in the back with little bits of brain matter stuck to it.
