So, for me, a pay2win MMORPG is any MMORPG where you can spend real money to get stuff that alters the gameplay. And it doesn't look like we'd ever get another MMORPG to which that doesn't apply. So how to deal with that? I see there three possibilities.
a) stop playing MMORPGs. If they can't deliver what you want (a non-pay2win game), then simply don't play them. There are enough other awesome multiplayer games out there, such as DOTA2, that do well without pay2win. So currently I do that, but I really like MMORPGs, so that's quite a shame.
b) ignore the pay2win part. Just accept that this is what things look like. A significant portion of the players want that, the companies deliver, and that's the way it is. Simply don't use the shop. Of course you have to live with the concept of playing a game that cripples you on purpose to force you to spend money, that people beat you in PvP because they spent more money, and that the guy you just congrulated for his awesome sword has bought it for real money a second ago.
c) treat the game like a subscription game. set aside a certain amount of money each month and spend it for stuff in the games pay2win shop. most problems of b) still apply, but the number of people randomly destroying you in pvp for money reasons will be smaller, and you will have the necessary basics to actually enjoy the game (a decent bank size, more than one character slot, an acceptable rate of gaining xp).
So what do you do?
