Every campaign I have played always ends with ‘Armored Turrets’ or ‘Monster Armor’. More than a little bit lame TRS
That’s how it’s supposed to end. Tougher Minions or Turrets that deal more damage.
Given how insanely powerful the Turrets are relative to some extra armor, this guaranteed adjustments on the final day lends itself to an unfortunately necessary strategy (presuming evenly matched teams, steamroll is gonna roll no matter what); As Monster, lose the first 2 days, taking advantage of the handicap. Win the second 2 days, teams are even, and you only have normal Turrets.
