Yeah, I don't really understand why the one note performance that sound like a horny yoga mom all the time (Halsin) is in that list. That´s what the majority of my co-workers sound like after a few glasses of wine without even trying. To Dave Jones´credit he only had what was written to work with and he seems very professional and doing the best he can with what he was given.
Other great side characters worthy of note: Sazza, Mol, Tolna Tome-Monger
But there really shouldn't be any point to making additional suggestions, because Raphael would be miles ahead of anyone in the competition and if someone else wins over him there should be riots in the streets.
