They had already fixed ilvl cheesing for CT prior to this, the recent change does nothing about that. It's so you also have to be geared for the final tier alliance raid you can theoretically do. So I couldn't queue for alliance roulette when leveling all my jobs to 100 because a lot of them I just got to 90 and didn't gear up much beyond AF. I only had Aglaia ilvl and not Thaleia so I couldn't do the roulette at all. I don't think it's a good change, it just seems like an unnecessary inconvenience. People weren't cheesing to get the first raid in a tier. Also it's annoying because now you can't gear up with alliance raid gear from roulette.
