how will spa, bsp be determined
i am assuming no bsp
as far as spa i mean its already a 2/1 pilot so idk if it would be overkill or not
also what maps tend to be swamps
also what table would the drac have to roll on for mech choice
Duels basically revolve around the Mech and pilot you choose to fight against them. The bigger the Mech you choose, the bigger the Mech they get, and vice versa (though there does seem to be about a 30-ton floor which they won't go below). It's a normal roll on the Drac Mech table for what the enemy ace actually pilots. Additionally, Aces will *always* have at least 1 SPA, and if your pilot has more, they'll usually get more.
No BSP during solo missions in general and duels in particular.
I have no idea what swamps in AtB look like, because I re-roll the living hell out of that result if/when it comes up. Generally speaking, you should be familiar with the mud rules (including the rules for getting stuck if you jump into a mud hex), and expect quite a lot of trees and shallow water.
