Alright, leecher here.
Finally found something worth sharing with you guys, used the search function and found threads from 2013 that had nothing to do with this.
Here goes, Thursday - Cleared BWL (all bosses)
Friday - Only logged my druid to do garrison missions, never went on my rogue wich I cleared BWL with.
Saturday - Logged in on my rogue, saw the eggs in BWL before leaving the instance. Tought this were rather odd so I looked if Razorgore were there. To my shock he
was.
So basically, this isn't a ''game changing'' exploit, but as for me who really want the bloodfang tmog this is great.
Going to kill Razorgore now and see if I get any loot. Will edit after it is killed.
Proof: Imgur
Edit; Wiped during Razor due to lack of concentration. Got no bosses to kill as of now. Be careful, can't confirm you get loot either.
