Suggestion: KI should create an elixer that allows you to tether your mount to your friends mount. (and if you had two other friends questing they could also buy an elixer and join the chain).
So you could easily quest with a friend without buying a two person mount. at the right price point I think it would be used a lot.
But wouldn’t it be kinda odd to be an elixir; then again, there’s one that instantly gets you to lvl. 50.
