As you might know, the final boss in SM armory is Herod and after he dies a bunch of Scarlet Trainees (non-elite level 30 mobs) that drop the Tabard of the Scarlet Crusade come rushing in. Something fun/useful you can do is kite Herod out of the room, kill the spawned Myrmidons and then kill him at the end of the hallway. When he dies, the Trainees rush in the room without aggroing you, giving you time to drink up or if you are of a higher level instant kill them when you jump in (with arcane explosion for example), allowing you to loot them easier as their corpses are in a line.
My first real try of contributing :wave:
