Seb vs 12azor from the final from a GR tourney back in 2010 (Patch 2.601) is probably the best game ever played in vCoH
Seb was leading 2-0 in the BO5 series. And 12azor gives everything he's got in this G3 to stay in it. This was also the game in which Seb introduced the legendary 'mine in front of the T2 and kill the M8' move ^^. I remember that 12azor spammed OMCG's, but got mostly Rangers from them

Who were tasked with taking down the KT that was camping the right side on Ango.
