"Paying attention to resistances was too hard, so we condensed it into just a handful of buffs that encompassed everything. Then decided that was clearly still mind-blowing to have it so trivial, so decided that rather than do our jobs and figure out a way to make it engaging and interesting, we'd just take the easy way out and completely ditch an entire gear type in favor of throwing more beefed up stats on gear to make people unstoppable rape-trains. Because that's what's fun."
