My main question is, why do a leveling roulette as a 70? You won't get anything out of it. Sure, roulette reward of verity, but you'll get more from the Expert Roulette or just spamming those lv70 dungeons. I personally reserve the leveling/etc roulettes for my alt classes that actually need to level up, like my NIN at 55 right now, or my PUG/ARC at 15-16.
