Not to discredit Reckoning's accomplishments this tier, but they just downed Garrosh on 25 on a 5 day schedule. Whether they put more time in, I cannot say. Yet I can say their previous tier performance was lackluster. A full month later than the top US 10m guild last tier, even worse than the previous tier. Nightmare Asylum, Avast, Modest have been pretty consistent over the last few tiers at the top of US 10m raiding. I know why NA hasn't downed it due to roster issues this tiers, cannot say why the other two haven't but could be something similar. Or it could be a slight tuning issue as well. Who knows?
