Last night, I got Orbonne in roulette, and one tank left. By the time we got to Cid, a new tank showed up and we finished the raid, and that's with several people being new. They're all relatively easy now, so I don't know why anyone would bother trying to limit what you get. It's people leaving (especially tanks) that actually makes any of the raids harder than they need to be, not the raids themselves.
