Given my specialisation at the time, tends to be directly related to how much I use my comrade. If, like in this case, I need someone to load (but not brace) the heavy weapon - they see a lot of use. But if I play something completely self sufficient like a weapons specialist, then they tend to just act as fire support and a source of more bullets/lasers/plasma/things that go boom.

Yeah, I have a few characters in reserve. I was thinking of having an abhuman up next in case of accidental death of my current guy. Probably an Ogryn because I loathe Ratlings...
