I posted my suggestion and all I got was trolls pointing out stupid information that I already knew (like the real damage Marauders do - guess what 20 damage was an EXAMPLE). People really need to stop taking the first opportunity possible to flame, and actually read what I said. If you don't like the armor types I suggested, come up with something else, but do not sit there and try to defend Blizzard's blatantly poorly though-out two armor system in SC2.
My proposal is simple.
Implement a new armor type for buildings and a new armor type for siege type units. Now for those of you who wish to provide your own take on what should be done with armor-types please feel free to reply. I want to have a real discussion on armor types here, not a flame war.
