I used to love the epic warhammer 40k stuff, i know from playing planetside, having giant mech's kinda makes it hard when your reduce to foot, it does add the great element of "my god, got to get the hell out of here" to the game, which is no bad thing. It does mean though games tend to be vehicle fests, there does need to be area's where close on foot melee is the only choice.
I realy like the idea of titan like mechs, large walking fortress's, slow, but can lay paths of destruction, maybe a way round the complete power of this kinda of vehicle would be close quarter fights inside these vehicles to take control.
I also like the idea of tanks, where one is driver and has no other choice but to drive, and one is gunner, it makes for smoe nice battles when you have a buddy along with you, and you have to comunicate well to be unstoppable.
Anyways, thats just my two penny's on the matter
