Ok I read alot of pages of material and cannot find the EXACT ideas I do not know the game in its entirity.....sooo here it goes.
Jumping vehicles:
General Concept: The ability to get into a neutral vehicle once yours is destroyed. If You eject from your mech, aircraft, tank ect...Or go from infantry to a vehicle
Problem:
You join the game in another form of vehicle and that is not working out for you and you want to change over to a new vehicle but not leave the battlefield.
Or if you eject from your Mech and have to escape and evade back to your base? What if all the Mech pilots slots are used up? Maybe you are closer to the airfield ot a Armored vehicle yard?
Solution:
Random neutral vehicles are placed on the map, APC's, Jeeps, Tanks and the like. These vehicles allow you to get back to your base quickly with some protection and even a mounted weapon or two.
Base Defenses:
General Concept: Each base or obective needs some sort of defenses, these can be manned by infantry after a base, mech factory, or other defensive position is captured.
Problem: Infantry is important but is not very useful after capturing structures and the like unless there is room for everyone to jump into vehicle, being a infantry guy has a really short life span.
Solution: So to kill off all those pesky vehicles and other infantry several types of the typical battletech base defenses should be availible to man. This will help in several ways, Keeps the other team from camping your base, keeps them from taking it over, stops a vehicle rush.
Defensive batteries (guns, missile launchers, beam weapons) can be manned on location or from inside the base for an extra defensive protection.
Stats :
Simply everyone wants to keep and track thier stats linked to thier user name, clan, group and or the like. So a system that tracks you stats just like on any other FPS would be a nice touch.
