Honestly it's a bit baffling that SE hadn't thought of this issue beforehand. I know people have mentioned that you get the same tomes and while true, you get much much less than if you do the weekly challenges which reduces how much someone might want to grind. It's a decent chunk that newer players / alts are prohibited from getting because they literally can't do the content yet. I will say though that this event is a step in the right direction, I've actually participated in it more than I have previous moogle events despite already owning the rewards. I hope that with the next part they adjust it so that the required duties are set to MSQ progress in order to prevent a new player in ARR from getting something several expansions ahead of them.
