Need Help Utilising Rpg System

I have made a bunch of classes(9) skills(126) a bunch of items(40) and special upgrades for each class called talents(5 per class).
Each time a hero levels up he can pick a skill, or level up a skill. I have 9-11 skills per class right now, but I can easily change this to let each class use all the skills or only some of them.
Each class also has special upgrades, the could be gained how ever.
A save code that is 12 characters long. Six of them for Items.
I have made all of the above

What I need is a small group of people to help me mainly with ideas and helping pick a map to make or give me an idea for one and then coming up with a way to ma
Some ideas I have come up with:

Battle For Duskwood
An Aos+Rpg combo, basicly an aos with side quests, I made this but did not like it very much. It could possibly be better if I had more ideas for quests. If you think I should continue this, I can upload the map and get your feedback.

Dungeon Quest
A map dividied in 3-6 areas. In each are there is a major boss. In order to advance to the next dungeon you have to slay him. This would have all the players playing togather, or against each and the goal would be to be the first player to finish the dungeons.

A Reverse Hero Siege/one sided AoS.10players+1 comp vrs 1comp. Basicly a fortress at the top of the map, your goal would be to fight your way into the fortress. Units would spawn from both sides and attack each other. The fortress would be very large compared to the rest of the map.

I don't know how to describe this one, but basicly it takes place in a city taken over by undead, and the goal is to sneak in and take out a litch, then escape.

Possibly some competitive maps. Like a two team castle defence. With the map split it two, and each team spawns units to attack the enemy team.

If you would like to help me on one of these, pls let me know here. I am stuck and Can't decide which to make.

Heres what I am thinking of making.
This map will be a siege style map. 10 players+1 comp against 1 comp. The 1 comp enemy will be the soldiers of a fortress in Outland, the ruins of the Orcs original homeland Drainor. Fel Orcs,Dreani(sp),Naga and Blood Elves will be in the fortress.
This map is arrayed so to the south there is a small encamptant of soldiers made of a mix of races. To the North is a very large fortress.
Each player chooses one of 9 classes each class with 9-11 learnable skills. And 5 special upgrades called talents. Each player also has a farm that spawns milita. These farms can be upgraded to spawn better units of different races. For example should a player aquire enough gold hey may upgrade to a barracks to spawn footmen or a crpyt to spawn fiends and on on. Once these units are spawned they charge to a fortress. The Goal of the Map is to fight your way through the fortress and slay the lord of the fortress, the Lord of Pain.

Ideas, input, anything.
I will need some help on some triggers.
I will do the terrain my self, or if some wants they can do it. I would atleast like someone to fix it up after I make it.
