Riding skill disappeared

My lvl 80 Shaman had 310 flying in wotlk and my lvl 70 had 280 before cata released, I stopped playing during ulduar but once I got back, I transfered server and recently changed faction. Both of them now have 150 flying. Ether with Cata release, mop pre patch or with the faction change, I lost 12k gold. And when I make a ticket? The “gm” (AI slop) first thinks Im still in wotlk, then thinks it a UI issue when I respond to the ticket. So now im here to complain (in to the void likely) and hope that a dev/support sees this.
