Except for common sense, or does that not apply either?
Refer to cosmetics being p2w because other ppl pay money to look better.
Oh and buying a game. Because paying for a game is the very definition of gaining the advantage of being able to actually play the game over those who did not pay and thus cannot play at all.
Fine, lets go with the idea that p2w has no clear definition, so then as stated above, its totally fine to make it include everything.
UNLESS ofc you grow a brain and admit that it gives you otherwise unobtainable items/stats/options. Is XP such a thing? You cant get xp without a boost? Sure bro.
You are literally arguing for stupidity here.
I dont even know how to take your logic seriously, but never the less you seriously wish to argue for it.
I can only repeat myself: Get familiar with the concept of pay for convenience.
Spending money on things you can obtain in game without any problem, just doing it faster/more conveniently.
Baiting players with time such as xp boosts and dungeon cooldowns are a perfect example for this. You can dungeon and level up perfectly fine without these items, but with them you can do it faster.
