Allow custom music tracks/sound bytes to be imported, so you can play them to any nearby enemies/as a warcry. These could be played globally (one time sounds only) or to anyone nearby who has vision of you. They would also be muteable per player.

I had a thought to make more than the one core map, but not just change the number of players, change the gameplay. I thought of a one-sided map where Radiant/Dire take turns attacking, where offense would have one tier 1 invulnerable tower and normal creeps and defense would have a normal DotA base. Also, a deathmatch map that was basically a huge forest with one shop in the middle and 2-4 fountains scattered around the map. It could be FFA or team.
