Ranked 5v5 should be brought back
Solo duo is just gambling to get an ok team and not a feeder. One person costs you the game in solo/duo. Getting better in solo/duo is a joke when you can't properly play the game due to trolls, ints, afks and the fact a lot of people not understanding macro.
Ranked 5v5 is the only mode where teamwork is a must and people lose or win as a team. Solo/Duo only develops toxicity and is a huge reason people do not want to continue playing. Many of my collegiate colleagues call this season absolute trash and there is no argument. The ranked revert, only reverted high elo when every elo was screwed by it. Riot is just letting us down season after season and honestly, every time I see an ad for league of legends it is false advertising. I can not recommend this game to anyone as it takes forever to understand the basics and then to learn the champions and to learn macro. The game is for competitive people and its being made for casuals.
