As it's free entry and rebuys are optional you can play the rebuy period like a freezeout and just adjust for people playing wider. You'll never have to "make bad plays" and if you are you're just adjusting really badly. If people are more willing to gamble then that's a good thing for good players, not a bad thing.

If I had a choice, I'd only ever play rebuys. They play deeper as people have much higher average starting stacks at the end of the rebuy period, people just hand you chips punting off in the rebuy periods, and the prize pools are much bigger than freezeouts with the same buyin because of rebuys.
