I know that in theory Mind Units are the point of the game as it's a score per side, but it really doesn't matter much on a regional scale. Has anyone noticed any other affects that fields have for players? Like maybe increased damage from xmps when attacking under friendly fields? Or increased damage from enemy portals when attacking under enemy fields?
It seems that linked portals give more items and more powerful ones when hacking them than unlinked ones.
Nothing seen when adding fields on the portal.
