The BETTER collab that FFXIV should have is

My dream collab as a fan of both games has been one with Wow myself
A fight against Ragnaros (most primal-like wow boss thats iconic) where you get some cool glamour weapons from wow, like hand of sulfuras for warrior, thunderfury for paladin, warglaives of azzinoth for viper that kinda thing. Would love to see a bahamut fight in wow with a chocobo mount and some iconic ff job armor for each armor class

I don't see it ever happening though since the tribalism between both games is too toxic. Which is such a huge shame
