my definition of p2w would be
anything that gives u an advantage over player that dont buy it no matter how small AND every purchasable timesafe which is no longer reasonable
also i dont consider content dlcs (like new zone + new class + new weapons) p2w if they are reasonable priced and not spammed (like at most once every 3 months)
what this means
1hp buff would be p2w to me
i wouldnt mind e.g. 5% purchasable xp buff
but ~50+% i d consider p2w
so if u have a f2p version of a game and a normal one and the servers arnt shared than i d consider neither version p2w the f2p version just has less content
