How would More Quick slots Break the game? A mage would not need to look up the spells they have learned so why would we need to. The Devs aim to give us full freedom to do everything in the exact way we want to do it, so they would probably even want us to have all spells/Abilities directly at our disposal. But with that said i agree That they will probably give the Whole UI a redo-work over when they are near release to make all these details they are going for easier to handle.
