In most RPGs you expect to see a healer, a tank, a damage guy, and a control guy. Deathwatch doesn't seem to rely as heavily on this setup, although I'm a little concerned about our lack of Apothecary. Are strange squad compositions a normal thing in Deathwatch?
Our Kill-Team is currently a Carcharodon Librarian, a Dark Angels Librarian, and a Flesh Tearer Assault Marine. We haven't chosen advances or anything yet, we're gearing up for our first game and might still gain a player or two.
