I've never really understood the people who disapprove of "min/maxing." It's a single player game, what does it matter to you? Also, are power fantasies not an acceptable form of roleplay? It's always especially funny to me when things get nerfed/buffed and those types get happy about it because it screws over the "min/maxers" since they're supposed to be the ones that don't care about stats, so why celebrate something you don't care about getting changed? It's a videogame, play it how you want.
PoE mostly is single-player (to the point where you can choose not even to be able to trade with other players). Min-maxing is very much 99% of a game.
