I've never been so driven to a LFG forum before in my life. It seems the community in LoL mirrors the one in Valorant; abusive, emotionally immature, and way out of perspective. That being said, I do want to play with players that want to win. I just keep one principle in mind; there's no sense in tearing down other players just because they don't clutch or share your twisted opinions on how to communicate with other human beings.
With all that in mind, I'd prefer people to be 18+. I'm currently Bronze 3 so I prefer players of similar skill level. If you're new I wouldn't necessarily rule you out if you have a desire to play well and have a positive attitude.
