Basically what I'm thinking is a map similar to Dota Style maps but more on the FPS side. The map will consist of these features. Tell me what you think, if I should do it and if people would play it.

-3v3, kill all enemies or enemy HQ for victory
-Gameplay similar to Dota, for example: Cpu vs Cpu spawns, 1 allied to each force.
-Defensive Strategies to protect the HQ and Offensive when attacking enemy HQs, for example: Slowly set up seige tanks to put pressure on the enemy or beef up your base defense.
-Highly influenced from FPS games, for example: Ammo system, Head shot system, weapon proficiency system, body armor system, interchangable gun system, rank ups(level ups), grenades, vehicles and a "miss" system to name a few
-no spells, just abilities unlocked by certain items.
-Item shop in base to purchase health recovery items, ammo and equipment.

Example Guns:
Marine with stim and a short modified attack range - SMG
Marine without stim and max range - Assault Rifle
Ghost with very short modified range - Pistol
Ghost with max range, high damage but very low hp - Sniper
Firebat with mediocre hp/damage - Flamethrower
Scarabs - Shotgun

Extras:
Grenades (awesomly triggered)
Proximity Mines
Smoke Grenade
Flash Grenade

Anyways lemme know what you think. Aside from my RPG I think I'm gonna start working on this. Probably an Installation tileset with some extended terrain

How are you going to implement that within reason?

The ideas are good, but some of them are too impractical to implement without modding/EUDs, or FRAGS.

Well why not just center a location around the SMG for example. I'd have a 3x3 tile location named SMG and center on him. If he has no enemies present in the location he/she is forced to ally all players with hyper trigs. So the only time he would actually attack is within these range modifying locations. No?

Two problems with that:
1. It's very annoying to have your alliance status constantly messed with. It also has a certain effect you might not want that I will not go into.
2. If there is an enemy in the 3x3 location, you can shoot enemies that are not within it.

ahhhh very true. well that just shit on my idea rofl.

Yeah, sorry, but this wouldn't really be much of an interesting game...

An AOS style with no spells and only an upgrade system would be kinda boring imo. Those things work in FPS's because you're actually playing them from a first person perspective. They just dont work that well in an RTS.

Also what Jaff said.
