There will be always dissapointed team(s).
It doesn't matter because of referee, schedule, injury, long fly, tactics (2nd squad playing) or tournament strange system (see WCH 2010 "better to lose" Brazil-Bulgaria 0:3 or ECH 2011 Poland-Slovakia 1:3) etc.
Unfortunately, we'll not change it !!! Please send petition to FIVB/CEV etc instead of blaming one or another federation. There is a right place where rules are agreed and FINALLY accepted.
If you want to comment it once again go ahead but I prefer to comment pure volleyball and qualification.
