People will call a game P2W if it makes money and saves player's time - games that are not P2W while being F2P do not survive or grow. Realm of the Mad God, the community didn't want to give the developer money, so the developer sold it off and moved onto Cash Shop mobile games since he couldn't make a living off his game which was good. We already said we are going to make them give no stats in the future. This is why we nerfed them the other day.
League of Legends is P2W, because it sells champions and EXP boosts. Any F2P can be classified as P2W. Hearthstone is P2W, it sells cards which increase your chances of winning.
We are just trying to make it as balanced as possible for free players. We're still in alpha please hang tight, we have a vision that is more balanced than 99% of F2P games and that's better than what you get typically. Having an economy around paid items makes it really P2W where grinding items becoming more of who has the most money. We are trying to not put capitalism into our Cash Shop economy even if we make more money for doing it. I personally am against this move, but @Rory is the leader and is his call. I generally am for a Cash Shop economy and have seen it work in Guild Wars 2 where players weren't too angry about it. We have to really get away from listening to the people who aren't willing to pay in the games industry, these people are causing the paying customer's to pay more. Although, at the same time if you look at game developers they have got really bad at DLC and splitting content from the actual core game. If DLC is so important to the game where it affects the user score of it, then it shouldn't be DLC. It is really that simple.
F2P games are a pro and con, this is why some gamers prefer P2P, because it makes everyone pay their fair share instead of the free players demanding everything for free. I hate the F2P model personally, but I have grown to accept it as a game developer and since P2P MMORPGs are a dying breed. It takes a very magical game to really get people to pay monthly for it, or a much lower subscription cost other than $15.
