It was CW but uGp just didn't put it on CW list like against PTM and some others.
It was a tournament without scores, uGp lost vs them in D1E server and won vs them on uGp server and they didn't count both scores. Many people talk about it without knowing what really happened... I knew them at the time and I know they would never accept a clanwar against D1E (they had akatemp and other dodgy guys)
ah and also their gamemode had a TK bug so one uGp member killed his own mate and no one added him
