Its kinda short and looks silly but i think its gonna be usefull for some of you.
Get someone with a crashin thrashin racer to aggro the first group (who will one shot it and then despawn everything), run down as a group, engage Hadronox, Bloodlust, and kill him before the adds even show up. (how to do the hadronox denied achiev)
Another usefull use of the Crashin' Thrashin' Racer Controller is : bosses aggroed by the racer will sometimes despawn after they conquer it for up to 30 seconds or so. So you can kinda skip bosses from instances ?
