fun ideas that will probably never happen: a mount that buffs you with full raid buffs besides flasks, or a mount with a mage with portals.
I really do wish the goblin hot-rod was available to players.
Perhaps a Breaking Bad meth RV. The sides fold down and there's not only a portal back to your faction capital, but bankers / ah / repair / etc vendors step out with gas masks on, and set up tents.
/ok, or maybe not.
I'd love a mount that has an NPC that could do pretty much everything. Sort of an all-in-one transmog, upgrade, reforge and vendor/repair NPC. Should be fairly easy to implement - Just add a menu to chose between the options.
The thing that annoys me is that the vendors on the mounts are not upgraded to current content so they are less useful after each expansion.
A giant flying bison that whoever rides it is the last air bender and the avatar team is a vendor a transmog guy a reforger a money bag and free loot mount. Gives current heroic xxxxxforged gear 2/2 upgraded. Can carry 25 people.
Best mount ^
I solo stuff. I do deepz. I raid. What else do i want? Oh yeah. loot. give me loot. Cookie for loot?
