Of course and so we can conclude that Divinity II is well-balanced (in my opinion) and with or without putting points into the Wisdom & Mindreading Skill gives in the long run the hero(in) ca the same level ! That's good.
THE difference is that you can level up faster in earlier levels and so
the level-up-curve is different .
But this is only true IF you playstyle of 2 playthroughs the same, except for Wisdom and Mindreading (like ChrisHLD and Raze experienced), but that's logical
I prefer to not invest points in Wisdom nor Mindreading. On top of that I choose always gold or another item by a quest reward and not the extra XP !
