Which RPG mechanics make you hurl your controller/break your keyboard in half out of frustration?
Personally, I smurfing hate point-build systems. I could never beat Diablo II because the smurfing skills were so vague on what is useful enough to invest in. It also made me not beat Dragon Quest VIII - oh, too bad you spent the whole game giving Jessica and Angelo points to weapons that actually deal damage, because you neglected staff points which means that you won't be getting any useful spells ever, at this point. Please, just give me a job system or something like materia/magic eggs so I can just mix and match in peace.
