I think he meant more that the spaces are so wide open, that the magnum is too strong. I agree the weapons are balanced, but it's more the map design and spawn points. All maps other than Plaza are rather small because of the movement, which is probably why it's most peoples favorite. I think he just switched thoughts, because if it was a bit weaker the map issues wouldn't be as big.

There is a level indication but only that it's NOT on your level, atleast as far I can tell. They can be above or below. Which is silly, these are very advanced machines, they can tell if the signal is above or below. I don't mind it, but on some of the height maps it's a bit annoying.
