I dont know where this goes so you can move it if you have a better place for it.
I think there sould be take map off option for mutiplayer so it could help with ambushs and I think it could make the fun because once you enter a place you see that dot or triangle and you know to get your troops ready. I would be fun to hide behind some trees while the guy sends troops out and attack them without him knowing.
And for sightings...
I dont think inftry can see through buildings. It will also help with my ambush talk and unless all the walls are blown up,inf in the war could not see. Same with close togther trees,big rocks,the and big walls.
