Chromas Should Be a Reward

I recently bought the Zac Sweet Chroma Pack. My first thought was: this is amazing. But then I realized that the amount of "amazing" wasn't really worth the RP I spent on it. I understand that quite a few Chroma Packs change the color of skins as well. But the ones that just change the color of a champion should be some kind of reward for having a certain amount of mastery, winning a certain amount of games w/ that champ, etc. I understand that the cost of Chromas isn't that high, but let's be honest: a simple color change for a champion shouldn't cost real money. And so that raises the question: why did I even buy a Chroma? Because I just wanted to be bubblegum. My first Zac game ever with that Chroma Pack resulted in a 4-0 victory for me. This whole post might seem like an extremely long amount of whining, but I'll summarize it down to two main points: Chromas shouldn't cost RP, and there needs to be more rewards for mastering a champion.
