Blizzard once again shafted my guild tonight. We are by no means a world top guild we started raiding late into cata but have made steady progress and are currently sitting on 1-13 hms working on Chimeron hm with a few 8% wipes last wednesday we decided on thursday to take one of our socials for our normal farm bosses as one of our healers cant raid thursdays. So Thursday nyt we went in and killed atramedes and maloriak on normal. Reentered tonight with our proper grp to kill chimeron on hc to get an error telling us the healer who has wasnt there on thursday for the 2 normal kills is saved to another hc lockout. I posted a ticket to be told by a GM there is nothing he can do as this is a bugg they cant understand how to fix then proceeded to tell us just kill it normal. I would like to have seen a gm say this to a guild that was mayby going for world first!
