While this is a completely reasonable reaction to the continued beatings your character has received from WotC, I'd still urge you not to give up on a character concept you like just because the rules are screwing you over. Maybe make a new proposal or something or see if there's some way to rebuild your character, but just because the rules are stupid you shouldn't have to change playing a character you like!
Plus, there's a half-orc reskinned as a bugbear (same Str/Dex bonuses, but proper support and no controversial oversized ability was the player's reasoning, I believe). No problems with re-skinning here.
*sniff*I hate half orcs
