Ah but those enemies that spawn a C are focused on my comrades at B which makes them easy to flank and pick off for both me and my team, once they start paying attention to me as well lol. Ypu also have the stragglers who try and recap A or C on their own which make for interesting battles. B is a great hold up but it can be easily flanked, especially when there is already a firefight happening from one side or the other. All I can say is that it has worked *shrugged*.
