I don't worry too much about withdraw fees on crypto casinos because I only deposit!
Does that mean you don't have any plans to win something and later withdraw your winnings to a private wallet? Are you playing until it's all gone?
The problem with withdrawal fees is that the prices are fluctuating at an bemusing pace so you will either pay really low or really high at a given day, if there is a way where they update the withdrawal fees in consistent with the current prices, that would be good.
There is a way, and some casinos have already implemented dynamic fees that take into account the current state of unconfirmed transactions in the mempool and change the required fees accordingly. In some other places, players are given a choice between a faster or slower confirmation time. Other platforms have static fees and you pay the same amount no matter the conditions on the blockchain.
