New map, need ideas/opinions

I'm building a new map which is a sort of original remake of the AOS idea.

Lords of Sanctuary - You and a group of friends were shipwrecked on a strange island, you search the island to find something but only run into trouble with the "natives" of the area. As you go deeper into the forest you find a huge abondened sanctuary (a big fortress sort of thing) You enter hoping to find something to live off of inside of it. You find everything you need, but your presence seems to have arroused some sort of ancient god in the wilderness, and he now wants to destroy you.

You must defend the sanctuary while pushign forward to kill the god.

Heroes - Heroes will all be custom made, with new skins and possible new models for some of them. They will be pretty powerful in the end, but weaker than average units in the beginning to make the game harder for people. They will all have custom skills, most of them are based on "Good" or "Light", there will be a few "Dark" and "Evil" heroes, but they will still be mainly bent towards the light.

Purpose - First with the other players you have to find the sanctuary, then obviously you have to defend it from the other side, this is actually a AOS basically, but once you have the "Sanctuary" you get the advantage (the sanctuary has some towers you can 'repair' and other cool defense things you can use, including a mage who cannot move, but can cast spells at long range.

If you can hold the Sanctuary for long enough, and find the other teams god and kill him, while still having the Sanctuary, he will not be able to respawn. (The gods can only respawn if their team controls the sanctuary) Then that team is proclaimed the "Lords of Sanctuary" and the game is over.

Any ideas for me?

hey sounds pretty cool

but i have a request
plz no more AoS's.
BNET is ready for a whole new idea. Something new and creative, not mods of other maps/genres

Hmm I guess you have a good point there... i'll spend the night thinking and come back with a new genre for ppl to work with.
