My point was just to post it as someone said it hadn't been done with 20-man in classic wow.
Anyways I understand that EV is possible to solo 4 man in full rakata or even columi when you know the fight and have experience - it's intended for people who just got to 50.
I like the idea, but sadly.. Makes HM fps kinda useless when EV is so fast to clear.
Ev is possible with 3 men. I've done it before
