My raidteam managed to get a server first boss kill while raiding Mythic Tomb of Sargeras in World of Warcraft:Legion. I was so proud of our teams achievement, I actually got a tattoo of the Mark of the Kirin Tor, a symbol for my mage character, in commemoration of the achievement.
This is a pretty great idea. Man, imagine how awesome it would be to roll extra Eximus on it! That would actually make me run the Sortie.
