I feel like the most solid defence anyone has come up with for the current movement system is that it's salvageable or they offer suggestions for improvement. Which is not great considering they've used this system for two other games at this point. I don't think I've seen anyone really give a reason that this system is actually better than the typical system used for cRPGs in any meaningful capacity. This really does seem to be the one point where everyone more or less agrees-the big divide is people who think it's totally intolerable and people who say that it just needs tweaking to some extent.
