First of all, sorry for my english. I was playing retail wow for some months but I cant pay it anymore for now, so I want to play on your cataclysm server. My wow is updated to WOD, and thats the problem... So, can I play cataclysm without having to download another launcher? Becouse my internet is not the best and I need a full night to download it. Thanks!
ignore the WoW Retail, you can play Cata by going here: https://www.warmane.com/download and select "Cata", it is just a folder and it does not requires any installation
yes, you can download the Client you wanna play from that link ( Wotlk, Cata or MoP).
Those client are ready to play, you guys do not need any installation, it is a just a folder with inside the "wow.exe"to start the game
