Great summary, as always. Some commentaries :
Vargas has no way to shoot, unfortunatelly
. He is not very well suited to the starter content and should perform well with dopplesnoders, spadassins, troupailles damnés ( with the quick stryke ( attack) skill) and deserters. In a nutshell, all allied troopers. A cheap guy, but not wonderful.
Missionnary can immune all your company members to Terror during one turn. This can be useful, especially against Demons. The healing aura only work on Papists ( so, at the moment, Dopplesonders cannot be healed by him...), contrary to all the other auras, which affect Christians as a whole
.
It is one of the drawbacks of Westerners : variety of believes in the same faction= can be a problem with specificsynergies.
Fencer is a very nice fellow to "guard" a zone : always let his pistol loaded to use it for a defensive shot.
Aidan can do the same, but with less impact on melee.
Anna Bogna can heal people a bit ( 3 Wounds) : I've rarely ever seen a player use it. Not a game winner, but this can be handy.
Sorry for my english...
