Not sure if my opinion counts for much vis a vis random magic, but I've only got ideas that excite me for a few of the magical schools or possible permutations therein: if random magic were decided upon, I would probably just go for one of the non-magical possibilities I see for a character. I personally would chafe under randomness dictating my viewpoint character, but I definitely see where Tominas is coming from, and the other side of the argument.
