Suggestion on ways to improve the free-to-play experience

As a player that rarely puts any money on video games I mostly play without any customizations and/or benefits gained by purchase with real currency. I do know that the developers need money too but I just feel that if a tournament style gamemode would be implemented we as free to play users will have a way to gain that one special skin we wanted for our main or any other optional skin. For example the most recent Dark Star mode was really fun and enjoyable and I really liked it, but hear me out here... A game that I started playing recently called Clash Royale has a challenge page where every week we get to take part in special events in which, if we play good enough, we could end up with a lot of valuable prizes. The same could be aplied to Lol, in the most recent mode there could be a challenge or a task which if you complete successfully you could get a dark star skin shard, or an icon or a ward. There could also exist ways we can get skin out of game (and no I'm not talking about the shitty Trist or Ali skins, but skins that could be gained by playing some other games like that one where you hook things with blitz that was released some time ago). Those are just some things I feel that could be added to LOL to improve the f2p experience. GLHF
