MNK will be new to people who never played it before but they'll realize pretty quickly how boring it actually is.
MNK's general gameplay still feels outdated as hell imo, even just the animations alone are outdated and underwhelming.

Just the overall loop is essentially just 1 2 3 when you really boil it down only that now we have less ogcd's.
The Blitz system got old so fast too and it happens too irregularly.
