I'd say runner is easiest for me. Everybody struggles at different duties. It's up to the fireteam to find the best fit for each member, and minimize weaknesses. Example: I raid with a guy who demands to take the same plate every damn time. He manages to [i]always[/i] die when detonating hus blight bomb. I have no idea how he can't adjust, but it's obvious he can't. What did we do, then? We had the ad patrol guy get his blight instead, and it seemed to work fine. he's also [b]that one guy[/b] who uses his self res immediately after he dies on the bombs, and then dies seconds later from the final bomb. [spoiler]his nickname is "guardian down" for a reason.[/spoiler]
