Make Community Events a bigger part of competitive LoL
LCS and ERLs are great, but for many not achievable. With the upcoming addition of Clash there is a big step being made in making 5v5 LoL achievable for many players. But there is still quite a gap between Clash and ERL play in terms of prizepool, format, etc. I think giving Community Events better support would be a good next step after Clash. Those events offer more practice opportunities for ambitious teams and can offer a more serious environment if its done right.
Right now we have the Event Finder website for Community Events, but it looks a little outdated and abandoned (considering its still in "beta"). If Riot could make a new website/platform and would improve the rules for which tournaments get to be on that website/platform so that you only get solid tournaments on there instead of the clutter that is Community Events right now.
P.S. If you want to improve Community Events maybe you can consider making a tab Competitive in the launcher that entails LCS, ERLs, College, Community Events and Clash.
