OK, so at least they made the effort to mention that players will be charged network transaction fees in their help section. So the info is not completely hidden and unavailable to players. Still, this should be clearly stated on the withdrawal page as well and not just as a note. The exact fee should be mentioned, giving players a complete overview of the withdrawal. If it's a bit on the higher end at the time they are making the withdrawal, they must see this so they can make up their mind to either proceed with the transaction or wait for the fees to come down.
