If I understood it correctly, the Early Access only includes about 1/3rd of the game (is that correct?) and in the final game, the level cap is supposed to be 10 (is that correct?).
Should both be true, then I want to point out that by the end of Early Access, most players have reached level 5 (some level 6), which means over half the level progression is already finished, but more than two thirds of the game are still to go. That's a bit of a pacing problem. If there is no more leveling up in the 2nd half of the game, that removes a lot of the fun & the incentive to do side quests.
The best way to prevent this would be to raise the level cap in the final game, above level 10. The other solution, slowing down experience progression, I wouldn't suggest that since playing a low-level party for long time is much, much less fun than a medium-level party.
