IMO it removes alot of the busywork associated with a luck or rng system. In the case of divinity EE there were Bodybuilding and willpower which each resisted X and X statuses. In order to optimize your build you had to have prior knowledge (guide or experience) as to the percentage chances the enemies have and the spells available to them. Levelling accordingly or you run the risk of perma-stun/petrify/freeze whatever. With the percentages removed and magic/physical armor acting as a blockage there is alot less information to perceive creating less room for displeasure. Yes there is still crits, miss chance and damage variables but those are easily played around. The new armor system makes the game more enjoyable for me whom has played barely any rts games.
