I've seen this debate before in several places.
https://www.reddit.com/r/MMORPG/comm...us_pay_to_win/ is a good example of one.
Some people will always call it Pay2Win, no matter what, while to others, there are notable distinctions.
It's really the same thing as the term RPG. I still refuse to call any game from the Diablo series an RPG, they're mere hack and slash games making use of some mechanics commonly found in RPGs even though those mechanics are not qualifications for the RPG genre. Ofcourse, there's also people who are pretty passionate at categorizing Diablo III as an RPG.
