The idea is that a mech that is defending their base needs more space to operate in. If you fit enough mechs on a base (2 or 3 is enough), there is not much in way of "stopping the cap" unless you...
1) Stand in the base like a statue to stop the cap, making it insanely easy for your enemy to shoot you down.
2) Run a really messed up circle around the base, only to deal occasional damage (scattered or concentrated) to the base cappers, only to be somewhat ineffective because you will occasionally "step off" the base area, which is actually limited for the defenders.
My proposed solution is to increase the base "radius" for defending mechs by 25 to 33% (maybe more) so that mechs defending the base CAN actually move around to defend it. Although this benefits light mechs more, the occasional slower mech should be able to fit within the radius and operate, rather than be limited to "makeshift" boundaries that are different on every map.
The capping radius for the attacker should ALWAYS be lower than the one for the cap defender...
