ok this exploit i found is for the first boss in the 5man trials of the champion for the first boss, works in both heroic and non heroic
exploit is for phase one if your group sucks at jousting
if a shaman pops their totems down before u start the jousting phase some of the mobs will aggro to the totem and just sit there evaded until you recall making it easier to burn one down
granted this exploit is small but i still figured i'd share it
