Removing system templates from GW / How sparse resources affect the AI

Lately while playing galactic war, I noticed how a new system appears very often: 3 planets, all on the same orbit, all quite large (can not be moved with halleys), but they only have 4-6 metal spots each. This is very annoying, mainly because the match will be long and boring (quite the opposite of what it's supposed to be).
However, it also does strange things to the AI. As usual, it runs around trying to get metal and does not build anything else during that time (that would be OK by itself, even understandable). However, if you happen to choose the same planet to start on, the AI will run into you very early (because there are only a few metal spots and you are next to at least one of them). If this happens, the AI destroys most of your buildings and most of the time you get a commander-only battle. And winning that is 50% luck and 50% using your Uber-cannon better than the AI.
So my question is, is there anything I can do to remove said system blueprint (if the game works that way), or some other solution I can't think of to avoid that scenario?
