Windows XP files still supported in new Windows. It just you cant backtrack. Wildcard can let Legacy players to transfer their character to Official.
I would say they are entitled to refund.
If you start to play ark a year back and you started on legacy server. There is no notification on client side saying legacy server wont be supported. New players do not know about the crunch or the forum. Wildcard should put notification on the client side about legacy status. If they can put new event notification, it wont be difficult to put legacy notification on client.
If you want players to play in unofficial, wildcard should charge player to play on official server not on game copy.
BTW if you cancel netflix subscription, you wont getting any netflix show. what do you mean getting all show after cancelling?
Wildcard should have made this announces before start selling genesis.
