One of the reason is vetaran players (nm players i mean) do not play pub games. i have been playing pub games after last bug cause some classes are broken and hard to play nm games, also few nm players around. whatever, people still plays pub games, i saw many 0 xp players. but no1 helps them during game and they die quick or dunno what to do. and probably they think game is not worth to play. i saw some nm players around but they do not help or tell ppl what to do. they quit at start if many 0 xp in game or trolling during game. now i am telling new players what to do in game and they appriciate it, and see them later another game. if you want to play nm games you need to recruit new people. ignoring them is killing game.
