What's the deal with Orbital units having so much health, and only two units to shoot them?

As orbital stands, the orbital factory has crazy health and can be built relatively fast... Only Umbrellas and Avengers are capable of firing upon them. Avengers are not so bad, as Umbrellas can shoot them down pretty fast. Avenger-to-Avenger fights are a different story. I see so many shots that miss their target even though the other avenger never moved. Radars... Radars are really silly. If I want intel, all I do is set a few orbital launchers or factorys to go to the opposition's planet, and patrol the place. They can barely do anything.I just spam them and I have constant visual on ALL of their base. It can break even the hardiest of turtles with enough spam. The only exceptions I can think of are the SXX and the astreus.

Someone else figured out orbital! HUZZAH!
