I wish they'd just put them in the Excitatron maps, at least as a final floor prize or something. I can't stand the roulette maps; I run them in a group of three with my roommates and it's nothing but damage sponge enemies for garbage loot and a pittiance of gil per floor. It's the kind of crap you get a miserable sense of relief from when the minion drops, not so much "pride and accomplishment".
