You should find players who don't rage.
I will not abuse other players at all. Even when I get abuse I will not abuse back, simply tell them to grow up. If you see me playing join a game with me, I don't have the attitude you experience from the naughty children out there.
Other players who have friendly attitude are Darkliath, Wraith84, and Warhammer_007. And also there's some noobs coming through now hosting games like Matt123456, calling them "No swearing"
My brothers also plays this game a bit as do I. We're mid level and can go head to head with pros (win some, lose some). We both experience the rage you have witnessed too, and he writes a blacklist of other players he has on a board next to his pc. We never join games with them and kick them if they join ours.
With the sale price currently on DG we're gonna get some more players in. Host some games "Demigod learning for nooobs" or something like that. It won't be long before the influx of new players become mid level players, then the pros will be outnumbered and Mid gamers like us can play and have fun knowing it is a game and losing is not a bad thing.
To all the childish ragers (you know who you are): Some people have a JOB and Family, kids, wife, School, College, etc and we don't have the time or the need to play 10 games+ a day. When the people who take this game too seriously grow up and get a balanced life, they'll wonder why they ever got so passionate about timing that snipe or chosing the right items or who's buying citadel upgrades. Sadly though there are some people who will never grow up.
