I think most of the older players are on classic but I dono, I mean its mostly adults w expendable income that fuels the game being a pay to win sweet baby inc masterpiece that it is… You never see Kotaku or IGN talking ill of Blizzard for a reason lol.
Also why I think swiping plastic for all end game rewards is here to stay, be a huge uproar if they rocked the boat. Blizzard cant do a ban hammer anyway, I mean the ladder would look terrible if a huge portion of it vanished lol. Corruption at Blizz would be top gaming news lol.
