Arcane Recovery is just another thing they changed, and even though it currently works well and very much in the spirit of the rules, it will be problematic later as Niara pointed out.
It all starts with Larian not wanting to implement the resting system properly. Short Rest is more than the 2x auto-instaheal button they put in the UI. Solasta has a separate interface for Short Rest and while I'm not a big fan of clicking dice manually heal X amount at a time, they are correct in making a proper event out of it. Because it involves choices and represents the passing of an hour in game time.
That said, AR could work as it is with a better interface where you would click on the levels you want to recover until the total has been reached. Instead of making a separate ability for every possible combination of levels.
The same UI approach plagues memorizing spells too. It already looks bad at level 4 when every single upcastable level 1 spell is listed as a separate level 2 spell. The actual level 2 spells are lost in that mess. The image of that interface for a level 10 Wizard scares me.
They just need to rework the UI and resting systems.
Too bad EA will be stuck at level 4 so we won't be able to really test how bad things will get without a revision of the UI.
