Is a heat shield the best thing to use? Right now I'm using heat shield because it works, but i'm wondering if there's a way the energy shield can be used in a good build higher up?
I have seen it used. However, I generally use an energy shield but I use a heat shield with dragon because it has such good heat stats already. If you want to be using a lot of heat/physical weapons, you need at least one heat module. Otherwise, you can use energy.
