I love Method and think it's great to see them get World First. But they had no competition. Paragon were in a different race, Blood Legion were about 3 days behind Method after the first reset and Vodka disbanded last tier. Also Stars were disqualified from the race (By Blizzard screwing over Asian guilds with stupid loot rules and lockouts)
So basically Method, without a monumental screw up, were guaranteed World First this tier.
Back in Wrath/Cata Blood Legion were finishing outside the top 10 every tier. You think they have improved since then? No. It's just all the guilds who finished ahead of them left WoW, so Blood Legion rose through the ranks 1 by 1 due to the guilds ahead of them dropping out. So you can;t really say Blood Legion is in the same league as Method.
