There also isn't anything to win via pissing matches in MMOC... yet here we are. "P2W is bad"..."WOW isn't P2W ARTARD!"
Personally, I don't think I'd call it P2W. P2W is buying characters that can't be gained via playing - or abilities that are more powerful than free abilities.
I WOULD call it Pay 2 Screw the economy... because all the money creates gold which punishes those who aren't paying by making things more expensive than they'd be otherwise. I can buy pots with gold... but when those pots cost 5x more because cash buyers are driving the prices up... shrug.
Until top guilds start "selling" runs through hard content - and that does happen occasionally... but even then THAT is limited and you'll generally not get TOP tier until right before it becomes obsolete...
