It would be extremely awesome to be able to use all these duel credits in something useful. Say a duel mode that allows you to pick the node and tier at which you are playing in AW. Once you find the duel target (which is hard considering profile pics), you could duel. Then you could pick duel normal or AW duel. It will put you at your current tier, then you could choose what node you would like to practice on. I know this sounds cumbersome but for some people like me I would love to duel a sort of a real world situation vs the normal AI which isn't as tuned as it would be in AW.
Thanks
