I notice when I play on defense side, I almost always run out of good turrets spots to fill.
Likewise, when I play on attack side, all the good turret slots are almost immediately replaced the moment a turret goes down.
Therefore, I hypothesize that attempting to kill turrets does not help units make it to the other side, because it does little to reduce the damage units take. In fact, by not killing turrets, the defend side would have to waste time disassembling to react to a change (that is, if they didn’t just spam missiles to begin with).
Infantry by contrast are easily killed by machine gun, and therefore I can minimize the average damage taken by using exclusively machine guns to keep trenches empty.
As a prove of concept I alternate between machine guns and repair trucks on a few different maps, occasionally rushing with high speed medium mech to grab supplies. It actually does significantly better than me trying to kill turrets…
So what do you guys think?
