Exactly, I'd wait a while as you'll be able to compete quite easily if your team is good enough to make it out of IV.10. Wait it out, feel out your opponents, but one thing is that you don't want to hold back once you do make your move for promotion. Depth is nice as it would have saved me quite a bit of suffering if I'd had someone to help take the spots of my two starting guards who got injured in the last game of the season and first playoff game.
