In C1, armour was the default mode. In a way for C2 "Power" (a combination of speed and strength modes) was the default mode, as in you had the speed and strength functions on all the time, but when you weren't using them your suit recharged. I basically want to switch Armour and "Power" modes.
Armour mode: Armour is again the default mode, when you aren't taking damage your suit recharges. There is no C2 webbing and your suit doesn't shine. There is no slowing of movement. Damage could work either C1 or C2. This would allow sprinting at a normal speed when your suit is out of energy.
New Power mode: Control wise this is activated exactly how you would activate armour in C2, with your suit turning a sixy C1 red. It allows you to sprint faster, jump higher, melee harder, throw further just like C1 as if you had both speed and strength activated at once in C1. Just that you would hold jump for a high power jump like C2
Cloak: Activated just like C2, except that you cannot now combine it with power/speed/strength modes.
This would deliver gameplay pretty damn close to C1, while maitaining the simple controls of C2. In MP It would mean that if you wanted to get from one side of the map to another quickly (as FPS players always want to do), you will have to be visible, and glowing red!
I think this simple change would have made C2 MP much much better
