I really think that map made the event unfun. It's not a bad map, but the Zulus spawn so far away that they spend most of the time running, the main point of the defense for the British isn't facing where the Zulus come from, and the side they do come from is indefensible. The fort was also far too big for the amount of players making it very difficult to defend. All those things come together to make it not fun for both the Zulus and British.
I think next week the map needs to be smaller and defensible, the Zulus should reach it quickly, and be able to flank the fort, but not just sneak in and capture the flag without anyone noticing.
