Casso, you don't understand. Elite, BnG, Team17, Hysteria should always be played on brand-new, generated maps. Of course you can edit the Elite maps, but only before you play it.
You could memorize jumps, shots and whatnot and play the same map again, you have the advantage of that. Could even try things offline then play that map in a league game.
Just learn to make good maps, takes like 30 minutes of learning, lol.
