i hate it. if the game doesn't give me a choice i don't worry about it and just focus on gameplay. if the game does give me a choice i become irritated that none of the choices are what i want. it's better to have no customization than limited customization, which all customization necessarily is.
but what i really hate is the western rpg skill tree nonsense. they all use the same three categories: defense, offense, and stealth/support, depending on whether the game is single or multiplayer. nine out of ten skills are utterly useless but you need at least five points per rank to unlock the next rank which has the skill you actually want. ninety percent of skill points are wasted and every character build ends up exactly the same in the end anyway. it's a completely uninspired boring system and yet every game made in the last decade insists on using it to the point that they're now cramming it into action games and watering down many popular rpg series with it.
