In a word: awesome.
Loaded Black took on compLexity Red (coL.Red) in the final in what will go down in arena history as the most entertaining final to date.
col.Red were running Mage, Lock, Druid wizardcleave for most of the tournament, but had an ace up their sleeve in the form of Reckful - one of the world's top rogues.
Loaded Black were running the disregarded classic comp of Rogue, Mage, Priest (RMP). Before MLG Columbus, RMP was considered an inferior and outdated comp.
After today, top teams everywhere will be scrambling to form their own RMP teams.
