One thing to consider when Paragon transfers over. The level doesn't transfer over - the experience does. This confuses some people every season.
Say you're level 200 on non-season and 400 in season - you won't finish season and become level 600. It would actually be roughly paragon level 426. This is because the experience required to get from 400 to 401 is a lot more than it takes to go from 200 to 201.
