So, I’ve done some strategy refining and I am pretty sure the opponents can’t buy towers during the play phase, which is a huge issue. When you cut off a route mid-fight, that forces the units to backtrack through your maze and take an alternate route. This can effectively double the output of the central section of your map (warriors track from their current position so doing more than this will be very hard), which is a huge player-only power boost, especially for aura towers. I haven’t actually done much grinding with it, because the tower selling system has to be used extensively between rounds and that is boring on account of being slow, but I am pretty sure the AI doesn’t keep up
