F2P is badly implemented when it sacrifices good game design for the sake of monetisation. COC is the perfect example of how IAP is ruining the game industry. Yes, its making good money, but the game is designed around getting money out of your pocket more than anything else. It is this 'design' that is causing problems in the industry, because now instead of people designing games to be fun and challenging to play, they're designing games around getting money out of you, while all other game design rules are thrown out the window. Yes some people will enjoy pay to win, but in my opinion those people are muppets and have no real appreciation for good, well designed games.
