FFXIV is a RPG and not some action game or fighting game. I really do like the realistic animations, they give the character weight and connect him to the ground. In so many other MMO it feel like the character is as light as a feather and often the steps don't even match the ground speed.
The only thing that really annoys me is the delay you have before and after all actions.
For example if you do repairs, character will stand around for 1-2 seconds then go down and after he is done it will another moment until you have your controls back… Same with shopping.
You very often loose the control of your character because initiating certain actions make him freeze for a moment.
