Looks like the russian guild "Exorsus" got the achievement already (http://eu.battle.net/wow/en/guild/%D...1%D1%83%D1%81/)
A little disappointed that the race was over so quick. Seems like Cenarius took longer than Xavius himself. Wondering if maybe the fight was undertuned? Well played anyway and hopefully the next tier will be more challenging.

Looks like it took them 8 hours for Cenarius and just 2.5 for Xavius. I really wonder what blizzard will think about this, cant really be happy with the raid being cleared this fast (at least I wouldnt be from a developer standpoint). Cant really remember the last time a raid was cleared this fast, naxx perhaps?
