I think a few more than 5% realize whats going on. Yknow, the whole "gamers slot machine", the addiction tricks they pull, and the high prices for minimal content?
A lot of us bought the expansion pass way back when, and we came back because we already payed for the shit. Now though, were prompted with another payment, and a lot of us are waiting until after release to decide if we want the shit. Many more than 5% will actually leave if TTK doesnt hold its value of $40.
