This is a truly epic video made by Merodyn of the Dentarg EU realm, AoE farming the Blood Elves at Black Temple for profit as a Paladin.
The Blood Elves he is grinding are located just outside the entrance to the Black Temple. Primarily he appears to be fighting Demon Hunter Supplicants and Demon Hunter Initiates.
The following is his analysis of the method to execute this strategy:
Use rank 1 Consceration, + if u want use a low rank holy shield, while pulling them. Always try to have your front infront of them so that the poison applies proper and dont wear off(usually use low rank holy shield when i take all the guys at the stairs(those that healthemselves) Then when u got em gathered go all out with full rank Consceration/avenging wrath. If u manage to get the elite demonhunter, just judge wisdom on him and use seal of wisdom, u wont go oom and he doesnt hurt more than a regular guy kinda. I usually just deaggros him by jumping off a cliff when the initates are dead.
Use Petrified ancient guard/figurine(figurine drops of last boss shattered halls and it gives 120 health each time u block).
Put a Felspike on the petrified ancient guard(sporregar shield, extremly easy to get, the skullflame shield might work aswell - lower dura on that one tho+ it might count as magic dmg, so it will kinda suck on the group that gives a magic debuff, compared to using the poison shield. Else, get alot of + block rating and + spelldmg gear
These mobs drop some fairly decent loot - as you can imagine, though, the real gold-maker here is the sheer volume of mobs you will be downing. Make sure to start this strategy with light bags! This can also work great for building up Scryer reputation.
