Cooller claims mouz was the only team hes ever been in that always kept the given promises and was professional at all times. They were always very helpful towards him and he was a friend with mouz manager or someone. They kept him in mouz even after eswc / iem dropped ql, despite he didnt win anything besides iem europe.
Hes not a mouz member anymore, but its kind of a gesture for their friendly approach. Afaik he had some problems with certain other (russian) teams back in the day and had been promised a good salary but the reality was a bit different.
Dunno what kind of deal he has with 102., but it seems it goes only for TDM matches.
