It just feels lazy to me, like the developer couldn’t be bothered adjusting the UI for consoles so they copied the PC interface and bound the mouse cursor to a stick. Some games do both at the same time, having menues navigable both with buttons and a cursor, but usually that makes all menus unreliable and unprecise as hell.
But it also limits you to 4 spells at any given time even on PC, instead of giving me a bigger hotbar. So I guess devs just middle-of-the-road interfaces that don’t please anyone these days.
