I play FFxiv because it is a tab target mmo not an action mmo, and im sure a lot of people are the same. What you find wonky is what a lot of people like about the game. I literally dont understand your point about jumping, its a jump, it serves the purpose of elevating your height, and more weight/ lag to it would just be a needless aesthetic change.

Also you dont quite seem to understand how much classes change between 50 and 70, but trust what everyones saying here in that its a whole other kettle of fish.
