^^^This, and reduce radomness in spawning of neutrals. I would like to see it this way:
Farther from Sun, lower the chance to spawn neutrals. Since HW's are near edge of the map, it's unlikely to get more than 1-2 neuts. Near sun, however, this number should be fairly high. This will reduce number of occassions on which player starting positions are very unfair (sometimes 0vs5 neuts, if enemy is equal skill and HWs are close you're screwed). This will also let Vasari use their scouts properly.
Before anyone whines "OP", number of neutrals can be easily adjusted, so Vasa don't get too much resources early game.
