In heroic strat near the last boss, there are undead mobs/elites that give rep when killed. Instead of wiping on the last boss in VH, you can just farm these because these mobs have a high respawn rate. Have fun rep farming :wave:
EDIT: sorry I wasn't clear, yes the mobs in VH give more rep, but takes around 20 seconds to kill each one. But the mobs in heroic strat aren't elite so they can be easily aoe'd down. Plus they respawn really quick. GL farming
