Is this an improvement to an already-existing feature, or a new feature entirely?
Actually improvement.
If an improvement, what original feature is it improving upon?
Improving Mapcycle by replacing very disliked map (actually disliked since previous versions).
How would this work?

Can you give an example in how useful this feature would be?

You guys who play AOW2 so often already know that map13: Lava Giant (map with flying lava rocks) is very disliked by many players because it's very choppy for graphic card - lot of fps loss. That's probably main reason. Always people transfer themselves to spectators, call a vote and map is always skipped.

So my suggestion is to replace Lava Giant with Sand Canyon II (map has main, front gate you can climb on to, place turrets on them, hills with elevators which has powerup crate in the center on the top, tiberium field is as you exit cave on the left which is the second entrance in the base).

To be fair, at least Sand Canyon doesn't lag like Crysis II on a Mac.

Dusk was working on a revamp, but if it's only him then it will take a while :V
