I dont know if any of you guys have been in serious competitive clans before but I just want to warn you that salt levels are gonna increase big time when they arrive. Peoples ego's are gonna get in the way and a whole lot of drama to boot. If your going to go into clans I recommend not getting too deep into the competitive nature. It's fine if you go in and have the mindset of you win some you lose some and not blame your teammates to heavily. You just tried your best.
I know naturally, clans will be fun for a while in the beginning (like in many other games). Just want to warn about the dark side of it too. I'm going to try look for not so serious clans myself.
While I haven't played too many teambased multiplayer games, I have almost exclusively experienced anger from the opposing team, hardly ever had I had my own teammates blame me or I me blame them.
Also... "salt" is not a bad thing for a community, people in general love to see anger and emotions. Humans are animals after all. So "salt" is only going to help the community, as it will be more exciting to watch for most people. Also "salt" is a great motivator, it gives people a reason to play the game
Also I'm already set with a clan for Splatoon, we're now just waiting for friend rooms to launch.
I think if you don't realize what level your clanmates are, it's your own fault if you lose. You should be able to estimate how good they are and how good the other team is to see if you can win or not. Not like you should never try to play with a team you think is gonna lose, but just don't expect to win.
And I think the best anger was in Mario Kart Wii, since people would just accuse you of using cheats if you do good
