[Suggestion] Try it?
Practice mode (sandbox?) and new alpha client is coming, so why not mix it up and add a "Try it" option on the store? IP/RP isn't cheap and sometimes people have to use 3rd party apps or watch videos to get champions/skins(details), why not let them try the content in the practice mode and purchase?
Every content would have "Try it" option, and when pressed, it would load a practice mode where you can try the content, if you like it, you can buy it
