You won't be able to use those skills, equipment, and the stats you acquired from the comp pvp setup in pve. You'll have to level him up in order to get all of that stuff in pve. At max level it is a horizontal progression model rather than the typical vertical one. What's nice about it is that the game doesn't change at that point, as opposed to WoW (as an example) where the game completely changes once you reach the level cap.
