Does anyone know how to restrict your custom soldiers from appearing as scientists or engineers, by any chance? I want the dudes I spend time customizing to take the field so that I can watch them grow powerful (or die), not get a static portrait before they disappear into the lab never to be seen again.
You supposedly set the character's role when you create them (at least in the main menu's character pool), no? But I've heard that's not entirely bug-free, and some stuff is still randomized sometimes.
As for the ADVENT soldiers' humanity, Neonivek does have a point. They've gone to extensive lengths to dehumanize and demonize the soldiers and remove any possible doubt around the fact each one is unashamedly evil. Not only the gene-modding, but the obscuring armour and the alien language. I believe that's largely unnecessary, and a missed opportunity when you could've had more human soldiers fighting for ADVENT, genuinely believing they're doing the right thing, that humanity's in better hands now, and that XCOM's just terrorists (i.e. like the average German soldier believed they were just fighting for their country in WW2). It could've led to greater narrative depth and interesting situations, but they chose to make a caricature. You're fighting absolute evil, don't think about it: all other humans are just too dumb to realize how patently evil everything around them is without your divine enlightenment.
Now, that's only that, a missed opportunity. I need to play more.
