I think the unbalanced distribution of powers makes the game much more fun. Often times, three or four alliances are fighting for what would normally be one section of a quadrant in a normal server. It forces groups to fight it out -- rather than everyone pick their corner and wait it out at sniping distance (most of the problem with WW servers nowadays).
That's why I favor putting all of the high value Unique Artifacts around 0|0, while converting The Gray into +200 VP.
Draw most combat towards the central area... but leave external strategies valid for those who wish to try.
