I like variety so long as it doesnt impinge on the artistic integrity of the world.

Like, for instance, so far we have only seen chocobos as a main source of transportation so anything other than Chocobos is kind of "eh?". If you get what I'm saying.

However, dragons and "magitek" (or something similar) do have their place in the world of Eorzea, so anything of that ilk will not make FFXIV too tacky. I should imagine anything SE chooses to implement will not be exceptionally gaudy and uglifying, but with Yoshi in-charge you never know.

I'd like to give him the benefit of the doubt but with words like "raid" and "questhub" being added to the otherwise sophisticated vocabulary of SquareEnix, I am not too confident.

Was there not also mention of glowing weapons?

Such things are really... what's the right word? Puke-making.
