Random thoughts from this morning's impromptu:
Biggest issue from this morning was sightlines imo, but those were probably a bigger problem than they would be usually since we only had about 4 people on each team. Still worth looking into though.
The cave area was really cool, although you should think about adding more paths into the cave, since Red only has one. Either that, or widen the main entrance.
The bridge area was pretty cool too, but I would maybe lower the bridge down to 128 or 192 units above the ground, as well as widen the bridge so more people can fight on it. Also, the deathpit is really strange - I think most people died in it because they were running backwards and didn't know it was there.
