If Issei gets promoted to a highclass devil within 5 years it's long, since he only needs to remain in his current rank for a while to get his next promotion recommandation (stated in Vol.11).

Regarding his aim in the game: he wants to rise in the ranks as much as possible so becoming champion is the ultimate aim but he would most likely be satisfied with the second rank if Rias is first.

He will build up a peerage of his own without relying on trading with Rias. He may take Asia and Xenovia but even that is not for sure as of yet. The only one who can be counted as part of his future peerage is Ravel.
