Contrary to popular belief the majority of decent european teams dont ladder either. Most of the top 50 games on obs, are ladder games played during the first round of an AT where everyone got a bye. Except for buho/AmeN/sqd, who all nerd ladder like mad.
If there are more tryhard europeans its only because there are simply more players, as a % of the respective populations who play, america is significantly more tryhard than europe. People like dragon just reflect badly on europe as a whole
