A lot of people are saying "just do ___" to get into Nod. But if NOD can just waltz into the GDI base to that one section without having to be creative about it, then that's imbalanced.
I.e.
A GDI Engineer runs to not. He hides behind rocks and trees to get into the base to avoid the long range of the Obelisk. Meanwhile a NOD Engineer runs right on in and isn't slowed down by having to dodge.
The issue there is that the NOD have a speed and time advantage to get to their location, and no chance of dying by the GDI Base defenses. Whilst the GDI DO have the danger of being killed by base defenses. That means the GDI have to mine and defend that section more than the NOD would have to. Which means using up their mines on their mine limit that could be used else where. I know people will keep saying "just mine ___" or dodge but if you want it balanced then both teams have to go through the same kind of loop holes in order to win, really.
But that's just how I see it.
