Nah, let's just bring Tanaka back so we can kill squirrels til cap with all our "friends" of the 15k subs! That's what XIV needs! It'll be successful guys seriously! We don't need good hardware or a modernized gameplay engine! Archaic and clunky is fun!
You want fluid animations you play something that isn't an MMO. I can't think of anything that runs like current XIV with a good response time for PvP or even PvE. The second you get KO'd while "realistically turning around to face thy opponent!" you'll be wishing there was a faster reaction time.
