First off, World of Warcraft is already by most people considered to have forms of p2w in it, so that’s something you can scratch off the list. Secondly, I am not going to tell you what your priorities should be, but speaking for myself, I damn sure know the least of my worries would be whether I could afford to pay for a video game being unemployed.
I was merely throwing out an idea of a F2P model that works for another company, not saying it was an idea I personally would want to have implemented in World of Warcraft. Obviously the model used by ESO works, hell the damn game has been around probably as long as World of Warcraft has.
And they’re still putting out content and expansions on a regular basis.
