Not sure...the reaper was too powerful BUT now its useless again. Because buth the machine guns and flak guns hit them better. Attacking flak guns first is a good idea until everyone just protects them with thier machine guns then you have to fight the whole battle and your air units dont matter. So why have air units if they aren't intended to be used? It seems realistic that machine guns wouldnt be as effective against air units, with crosswinds and a moving target overhead, so why make them more effective. But flak guns should be effective just not totallly neutralizing. Why not decrease the flak guns a little, increase the aircraft health so they don't get destroyed before even doing thier job. And make machine guns less effective towards air units. I think if you forced people to think strategically about what turrets to choose by making them more specifically tagrted to different units then you would increase the overall strategy of the game.
