Because the Iconics are heel champs, they don't have to be dominant. THey just need to be be able to keep the belt when it counts. Flair said back in the day he lost 3000 matches, but won 16. An exaggeration to be sure, but the point being that the type of heels they are don't require them to actually win a lot. For heels, being potrayed as beatable actually is one viable way of booking champs.
