My only issue with the "ugly face" consequence is how absurdly "relative" it is. On drows and half-orcs the change is barely visible, but if you want to have a pretty human or elf, going to half-illithid route is a no-go. You either get an obvious power buff, or a situational RP nerf. It is a weird design choice for sure. Turning ugly should at least interfere with romances. Or come up in any other way.
