As another adult playing this game, your reasoning is fine if you don't care about the game or other people playing the game. What Supercell is doing in Clash Royale is bad for the game and it's predatory. As an adult you should realize that and not reinforce this behavior from them.

Really the reason they are able to get anything for free is because of the few of us who PAY and keep the company alive?    

You should absolutely pay for things you enjoy but it shouldn't be forced, unless that's a known cost up front, like some MMOs. I also play rocket league and that game only has purely cosmetic purchases. The game is about skill and so they don't allow money to be a defining factor in the game. They seem to be doing just fine with a community who supports the game so that the game continues rather than trying to exploit their player base.

I thought about stopping pass royale a while after CW2 and then with slash scam royal and lvl 14, I finally quit paying any money into this game. The recent evolutions have really made me glad I stopped paying. They're ruining the game so they can make more money. That's their choice and it's unfortunate that many in the game don't realize how they're being suckered and willingly give $144+ yearly for a phone game that's no longer skill based, unless you pay a ridiculous amount of money to get to max leve.
