I try to keep a list of players that are particularly rude, but I wouldn't usually bother to post a warning about any individual, however this player is an exception.
Most players, including myself! get annoyed and frustrated at times and express this in chat, but I've noticed some players (those of the lesser penis?), like to go the extra mile and can be firmly placed into the "jerk" category. A shining example is the player, "Nomilirac". Avoid partnering with this guy. Seriously. This is a case of extreme disproportion between ego and ability, this really guy knows it all and isn't afraid to tell it like it is.
This is of course despite being almost entirely ineffective and although having notched up a "very rude" warning note to myself I decided to give him another try today. My god I got less abuse from the neighbour whose glasshouse I broke with my unruly football when I was 9. I think getting my ass out at work while shouting racial slurs would engender less bad mouthing and opinionated venom. My crime? Being matched against a better team, having a poor combo (I hadn't made the bad choice) and a weaker Rook player on our team than on the opposing team. And who hasn't been there?! So instead of a dignified retreat, a pleasant gg and moving onto the next attempt the game ended in pre pubecesent "sighs", random "wtfs" and the customary smacking of the "End Game" button to find relief.
Do yourself a favour and avoid.
