2010 was when CS was dying. It was not a better era.
mtw were meh, mouz were meh, and SK were not that good.
Cogu had to deal with all of the good NA teams like 3D/coL/JMC/u5 while also dealing with teams like NoA/mYm/g3x/4Kings/Begrip (swedish and CIS), VP, wNv, Project.kr....nvm the Swedish scene with SK, fnatic, and NiP. Oh yea..let's not forget Neo and the Poles who really came on in 2006/2007.
Cogu's era had to deal with more teams in more regions. markeloff had to deal with only a few teams as the game was dying. 1.6's peak was 2004-2008. The game began dying after that when tournaments like Arbalet Cup were big. Before that there was CPL/WCG/ESWC/Kode5/GameGune/Dreamhack/etc etc. markeloff had IEM, Dreamhack Arbalet and not a whole lot else.
