It was on AB too. Name of Anguis^^^ and it is a Drakota. Group x 2 mob. It was orange to 20 and blue to 24. It had a couple of "babies" - Drakota Adepts^ with it.
We formed raid - limited to 2 groups. And it destroyed us twice. I think we had it to 97% on the second try
. I think you would need both groups to be solid 26s to have a chance.
This game is really not designed for raiding. All of the buffing restrictions which make sense in the group game become ridiculous in a raid. You cannot even rez a member of a different raid group. Moving between groups is out of the dark ages. And the numbers limitations are just silly.
