You forget that they're also a company that wants to make money.

Riot doesn't just make the game only for fun. Like any other company, they also made the game to get revenue and profit, so while your idea is correct in a consumer's sense, the idea actually destroys some potential profit because if you make a mistake and buy the wrong champ...

Well you used up all your refund credits. Guess you just have to go buy RP!

More RP bought = More money.
