Congratulations, you too fell to finding the wrong enemy guild. Not long ago someone claimed this exact guild to be their opponent when in fact another one with a pretty similar looking name was the real one.
Dunno bud...i can live with "S happens"...or with "ups...unlucky fix"...once...twice or more times...but so many in a raw, and we are not only ones who got this issue as one can see by more and more of debates about it on forums, it is narrowed to the fact that MM is heavily unbalanced atm, and all of this is in hope of CG fixing it a.s.a.p.
As end user of this game only thing i know it is not fair sport and it is not something that any true competitive player wish for playing same content in game.
