Random Idea, Thoughts?

So honestly, I don't really get on these forums/boards at all, but I was thinking about a random idea. If you play other video games, I'd imagine you kind of know that a popular trend right now is opening "packs" to unlock things such as characters, items, etc. An example would be like NBA 2k16, you open "card packs" to unlock new players, items, etc. Or the game Plants vs Zombies Garden Warfare 2, where you open trading card packs to get new items, players. Well what if league of legends hopped on board with this trend? How do you think it would be to buy packs with RP to unlock stuff like skins, champions, ward skins, runes, etc? How do you think this would turn out? :D
