There are 2-3 threads showing how to farm consortium rep aswell, but those are off the first boss. Not the last one.
I recommend doing this @ 80-85.
1. Enter Mana-tombs (HEROIC)
2. Clear everything apart from the last boss (Or just skip everything, but since ur farming rep anyway, its smart just killing everything you see.
3. Engage the boss, but DO not attack him. He will spawn adds every 20-30 seconds (or something like that)
4. Just go afk for some minutes, kill the adds and repeat : )
The adds give 22+ rep if you have the 10% rep increase from the guild perk.
