Why in the world did riot remove 5v5 teams

ok ok ok.. calm down, i know its been a looong time since they removed it. But why did they? 5v5 flex feels wrong, you arent a team, sure they added clubs, but you don't have the competetiveness, before it was soo cool to be in the top in 5v5 teams but know its just the players i feel like they removed the exciting part of it.

And its much harder to find people who wanna play 5 flex. Because you cant ask "Can i join your team? so we can play 5 man?" now you need to find 4 other players and ask them if they wanna flex? "But why not just play 3 man flex ?" .. if you use your brain you can think to the answer "Its not 5 man flex, you dont speak with them over discord, skype or teamspeak you have no connection, sure you can afterwards just ask them if they wanna play with you and your friends but the chance is low

I miss the feel of finding a "team" and then just play 5v5 and make strategies.

But if someone need one player then ask me because i wanna find someone who wanna play 5 man flex and take it somewhat seriously. Im plat 3, Adc main but can play decent jungle, and can also play top and mid and support just prefers the other.
