It depends on what it is.
FF14 has a lot of mounts and stuff from crossover events, but it’s a sillier game and takes itself less seriously.
If I saw someone riding the Cat bus from Totoro in WoW, then yeah lol I’d probably be like “What the hell”.
It’d fit just fine in FF14 though, because they already have that kind of stuff.
There’s a snowman mount that you ride inside of lol, it’s all silly.
It’s just the standard WoW has set for itself, really.
Most everything you see in the game, basically ‘fits’ with WoW’s artistic direction n’ all that.
Like the Mountain Dew motorcycle- it looks like something the Burning Legion would make and have. It fits.
