An excerpt:

"2011 was huge for DotA 2 as well as the players associated with it. The buzz among the community was off the charts as many famous ex-DotA players began showing up on DotA 2 servers and events. The Ukrainian giants had silenced the competition with a loud thud but instead of a cold war and complacent whimpers from those who did not take home the gold, came a flurry of changes that have paved the way for more players, teams, acquisitions and game plans."
