8 human beings, with only one of them possessing the Echo lorewise against a Garlean turned dragon God, a creature that was a match for Omega, because he was infused with both eyes of a member of the first brood…
Right, it was completely unfair against us, and still we kicked him
And, if he ends up becoming the "long term big bad", chances are we'd face him into another 8-man instance, so the setup would be the same. It's very different from our rematch with Nidhogg where he was clearly restrained the first time.
