A suggestion on Ranked Flex ( Integration of Clubs and Flex Queue)
Hello, I've been playing league for almost 3 years now. Before I start, please excuse me for my poor English since I am not a native speaker. This season, ranked queue type has changed dramatically: from Dynamic Queue/Team Ranked to Solo/Flex queue. In short, I am pretty sure not many people like it. In my opinion, the big mistake you made here, is removing Team Ranked. Team Ranked was something you can show other people how good you are as a team player. Also, the team ranked leader board which listed best teams in the region gave many players motivation to play as a team. Now, what's left? We have flex queue leader board in place of team ranked leader board. And, the flex queue leader board is essentially not much different from solo queue leader board because it only lists top "players" instead of top "teams."
One solution for this is to integrate clubs and flex queue. Let's call this new queue type "club queue." This queue will have mmr based on the clubs. So, all members in a club will share the same club "mmr". A party of 1,2,3, or 5 players can enter the queue. (just like the current flex queue.) Yes, this means that you will play with people from different clubs. However, the lp gaining system will be very different. Let's say you were in a party of two with your friend in the same club and won a game. Also, let's say you got 30 lp from it. Then, your club's lp does not go up by 30. Instead, it goes up by 30 * 2/5 because only two members of the team were in your club. For another example, let's say you are in a party of five, all of whom are in the same club. If you win the game, you get the full 30 lp for your club. The club queue's leader board will list top clubs having highest lp.
I know my idea needs much more elaboration. However, I hope this is somewhat helpful.
