Hang on, wtf are you talking about.You mean, if I go out and repeat an activity, over and over, my character will get better at it. Almost as if it were gaining experience and grew more powerful from it.Why dont we call it "leveling up", and make each "level" harder than the last and turn it into a developmental grind of sorts. That way if I have successfully killed more things with my fireball I will be better at throwing fireballs than you.I apologize for the over the top sarcasm. What you are wanting should already exist In the form of levels effecting your stats. ESO had a gimmick like this and that's what it felt like, gimmicky. I'd prefer as we get stronger, perhaps having to choose a more powerful single spell over a few lesser ones. Divinity original sin 2 has a great system where you choose how many spells you can have on hand at the expense of power or life or mobility etc. And the more powerful the spell the more memory you needed set aside.
