I used to ride like that and I was worried all the time about my chain needing to be taunt. It doesnt need to be like that. Chain rings are not perfectly round unless you buy a super expensive high-end one. Thats why a chain ring will cause you to have tighter spots in your chain. Don't do anymore chainring upgrading, you're fine.
