Wow, are you serious? The main point of slayer, which is a skill, is to gain XP in it, not the drops. And ring of wealths suck, they increase rare drops, not drops in general. And most slayer monsters only drop one rare item, so I, among many others, would rather hit more often / higher than get an extra few hundred K. The only "good" slayer drops anyway are whips and Dark Bows, everything else is really cheap, and not worth the time lost while not using a Berserker Ring / Warrior Ring.
