Says the guy who's 7/10M raiding 5 nights a week. My guild has killed the same number of bosses and we raid less than you, where is this discrepancy lower down in the progression curve that you claim exists?
There are less mythic NA guilds period and there are far less guilds raiding more than 3 nights a week. There is no skill difference between NA and EU, there's just more of you guys. Outside of Method/Paragon of course.
