[Rolfski]

1. On a strategic/world level, I prefer adjacency/hexes. My ideal Auraxis would be a globe full of territories (who are now called continents) that you fight over and can invade but have consequences in the way you invade them. Sea, airborne or behind enemy front invasions should be possible but are risky and have severe logistic/resource consequences, just like D-Day landings.
   
2. On a tactical/territory level however, so once you invade/fight ingame, I prefer a system that ensures great battle flow and lattice is probably best for that.
