Its because elites are slightly taller than spartans. I had the same problem before. Even though the elites can clearly enter the are of the teleporter, in game teleortation rules say that the elite should not be able to teleport and therefore cannot.
I don't know. Still think it looks like it would be broken. There are countless other issues with Swordbase than the gold lift and that entire part. The entire flow of the map is just constantly upwards, and once a team has a setup up top, there's no reason to switch it. The problem is there are far too few, too exposed and too long routes upwards, which makes the flow pretty linear. The entire concept of having two sides split with a big, empty void like that, with completely exposed bridges being the only way upwards just doesn't work well for competitive games.
correct, but I believe to have added adequate cover and maneuverability between the sides. I agree with your statements for the original map, but please download my version, and keep an open mind!
