The Conqueror's Battlegear is available as a quest reward from tokens found by squishing gigantic bug bosses in the Temple of Ahn'Qiraj. In fact, this was the first time World of Warcraft featured bosses dropping tier tokens, as opposed to specific tier armor.
Be sure to loot all the bosses you can in there, as they also drop Qiraji Lord's Insignia tokens, as reputation is required for some rewards. You'll also be needing a number of scarabs and other items found within the temple to complete each armor reward: Quest for the Conqueror's Breastplate. A couple of lookalikes are also available for some of the pieces.
She put quite a bit of effort into acquiring the whole set. I'm glad she shared her set, which shows that not everything is a smorgasbord of items from around the Azeroth and Draenor. Sometimes the effort of putting together a complete iconic set is just what the doctor ordered. Paging Doctor Exeçutìe, report to Ahn'Qiraj. Insectoid evisceration required, stat! :p
