The goal is to be able to solo ultimate raid. Also, when I start a ragnarok raid, most of the time I have to solo that for the first 10 mins anyway so going full offense wont work.

And if I have to, I can change ambush/sniper shot into shingen's 20 burst gauge EX skill and use hraes anyway, nothing of value is loss

Both aether and frigg have that team crit buff, which didnt stack with cybele's. So I wonder if hastur's atk buff and damage benefits me more than cybele
