I still wish they would have kept poe 1's casing system, with per rest spells, it feels weird to me to be able to cast so many spells every encounter. And yet sometimes i wish i could cast more spells of a particular level in a fight.
I'd rather say that playing a wizard and not casting spells is much more weird.
Well, you would not not cast spells in PoE 1, especially later on with the per encounter spells. But you could not go all out in every fight (or you could but then you'd have to rest a lot).
I view spells more as a strategical resource that you have to use wisely when you need them, i guess that's from my old D&D days.
