Oh look. Another horde mount that isn't a horse, gryphon, or wyvern.
Eggs droprate for kuafon is still utter shit. Current guess-estimates say ally equivalent will be a chain for the beemount next patch. You can mount them regardless of faction once attained.
Caustic Mechaslime (6), Gorged Gear-Cruncher (15), The Kleptoboss (33) share spawn in the same tunneling-network that has three different entrances. Drill rig daily needs to be up to see any of them. Blizz-RNG may make some rarer than others so happy hunting realm-jumping! So far on EU-Khadgar I've only come across mechaslime these past two weeks.
No. And when Alliance players complained they were told to fuck off, it wasn't that big a deal, he can't even fly after all.
Lol.
But hey all you have to do is pay for a boost, level them up, grind for a rare drop, do the questline, and then you too can have it. But fear not, the bee mount will PROBABLY be faction semi-exclusive too and they won't just make it a drop because the Horde player base is what keeps the lights on in Irving California.
