Im totally with you on this, I have some Vibate and Funfair on Binance, and to withdraw them to MyEtherWallet we are talking 10% of the value, a ripoff indeed!
I dont really know what to do about it tbh. For the moment Im leaving the crypto in there and avoiding using the exchange just for this reason.
If the coin is on Crytopia, then trade there instead. The withdrawal fees are very small, however you may find yourself with a beard by the time they land!
