What exactly is it you hate so much about Domri? I mean, I get he's an annoying teenage brat that would be a pest to have around. But when I personally dislike characters in Magic, it's usually not for who they are as people but for what Creative does with them (e.g. massively retconning their origin stories or involving them in timetravel paradoxes). I think judging from where he's now, there would be a lot of room to grow for Domri.
It's not just that he's an annoying, dumb, chaotic little brat, it's that he's all those things and is
rewarded for that behavior. He lives in a society that idolizes such actions and he's a twerpy little golden child. The only thing that he has going against him is that he's shrimpy, and that's mostly just given him an annoying complex to live up to in spite of it.
I don't care what a character can grow into. Joffrey could have grown into a good character, but I wouldn't want to be on that journey if I can't stand the little **** in the first place.
