I am a long time GM of Deathwatch and am finally getting a chance to play. However, I am having trouble deciding on a character. My favorite Chapters are Ultrmarines, Dark Angels, Imperial Fists, and Carcharadons. I want to play something very group oriented so I know I probably will play a Tactical Marine for all of the Squad Mode goodies. There are so many chapters with so many good looking squad mode abilities, but which are really the best? Thank you.
