I know I'm nowhere near getting into the postgame of the expansion, nevermind Alexander--
But having seen the boss of Floor Three in the CE artbook and online strategy videos makes me really REALLY want a minion of him, "physics" and all. Even if it's crafted from material that drops only in the raid or (dare I say) from the Mog Station.
Heck, /poke it to get him to shift phases on command!
