I don't know that be a cool idea... I mean they've simulated battles before in solo duties even the original castrum meridium was like that, Baelsar's wall, doma castle, ala mhigo, Ghimlyt dark...
That cool solo duty in Shadow Bringers where you Alphinaud and Alisae come in to save the day.
I guess the idea is there are large battles going on around you but you and your crack squad of attractive and smart team members are going in as a vanguard.
