They're fucking garbage. But, if you look on the
mount store pageall of the rep mounts are clearly there and were input in the game but they decided to charge people 25$ instead of using them as rewards for literally the most boring as fuck grind since Wintersabers in Vanilla. "Enjoy your boar, faggot" seems to be the motto.
I didn't hate the goblin rep too much though, it was still grindy but being able to kill ogres, find treasures, or kill rares for turn in drops is alright. Laughing Skull and it's dumb shit "Just go kill 7000 mobs" grind was dumb. Not that I had to do it, but I feel like I should've been better rewarded for it.
