Royal Militia has participated in all of the major world events this game has ever had including Azuregos/Kazzak, Green Dragons, and the opening of AQ. We raided MC when intellect was the dominant stat on caster gear (the first time),  fury warriors were the best (and only viable) tanks, and mobs only had 8 debuff slots. We raided BWL when repeated battle shouting was still a viable strategy. We were there for the opening of Ahn’Qiraj and we were attempting C’thun BEFORE the teleporters were added. We raided Naxxramas at level 60, when world buffs and 6+ warrior tanks were necessary for some encounters.
