I can't say I've had any similar experiences. We ran 16T sprockets with untensioned chain and it lasted us two regionals and champs with absolutely no fails.
You are correct about the chain loading and for that reason I would say that it's best to run the largest sprocket you can on your drive. However on this drivetrain it looks like the 22T sprockets OP is using are too large and the next smallest size is 16T, that is the reason I suggested using 16T sprockets. Also, I'm pretty sure 16T is standard for WCD's, and I've never heard of WCDs popping chains.
Tell someone familiar with FIRST that you won a regional and they will congratulate you, tell them you won a chairmans award and they will celebrate you. - Brandon Holley [more]
