Balancing can be difficult. More stats or more complex formulas make it easier to fine-tune player-enemy interactions. That said, as a player, I also like to understand what each stat does. In my opinion, developers shouldn't make it easier for themselves at the cost of confusing the player with, for example, an 'Attack' and a 'Strength' stat which *somehow* (that is, combined in a convoluted damage formula) boost physical damage dealt. The player should have an idea how to maximise physical damage dealt without searching a wiki.
