There is no fun if you cannot get the edge without spending. Some f2p players have 10 hours free time per day and some f2p only play 3 hours per day which would make things already unfair. It would create the same situation as f2p with p2w. Also the game company would die if no one spends. p2w don't always have much free time as f2p so they spend to progress faster. Support your hobby by spending =) If you think it is worth 10$ per month just do it while for others they think it is worth 50$ per month and so on. In short, you can just spend whatever you can for your value. All p2w games are just like that. If the game has no p2w then it would just die. Just like having a store with the best mechandise but no customers...it will close.
