I find the scoring very well balanced. 0-2 points per turn means making 0 to 120 points from AAR writing, which is a very nice incentive.
I also do not think that newbies would ruin the game balance at all. Since everyone gets to see everyone else's strategy, at least rudimentary, everyone is on a semi-equal footing.
And simply going for scoregraphs is much easier than going for world domination. You don't need to master it all, just a few aspects.
