every game that's f2p is p2w by ur definition.

Your definition is completely ridiculous and stupid cause dfo's fundamentally a pve game and you can compete perfectly fine without paying which are 2 aspects p2w doesn't have.

The other, more accurate definition IMO, is that if you can make micro transactions that give you a serious advantage

the actual definition of p2w is being impossible for a f2p to compete with someone paying money thus paying to win. Your definition would fit every single f2p game excluding dota2.

Even league would be considered p2w because rune pages and a wider champion variety would be considered a massive advantage for anyone without everything unlocked.

It doesn't matter if ur bronze-challenger having access to 10 set rune pages and the entire roster fundamentally gives you an advantage over someone with 2 rune pages and 20 heroes.

over those who don't make those transactions, then it's pay to win

you're actually massively stretching the meaning of p2w to the point that its utterly worthless.
