I think arcade mode should have unique maps for each commander. I'm trying to beat arcade mode with each commander but it gets kind of boring with all of the repeated maps. I usually don't need to change my strategy based on the commander so its not interesting seeing the same map repeated. Also I'd love to see more asymmetric maps in the vein of War Room maps from advance wars. All of the arcade maps only achieve difficulty on hard by giving the ai an extra swordsman to start and doubling their income, but the ai seems pretty bad at securing territory so even the extra unit doesn't help them there and it seems bad at choosing what to build so the economic advantage seems wasted. I think giving the ai more territory to start could help. It would also be great to have 1v2 or 1v3 maps in arcade mode.
