Gleba was a good example of that for me. First the waves were really weak and barely a consideration. Then the medium enemies started spawning including the fat crabs and shit started getting ran over. And because of my laser hating autism it took me until the discovery of tesla towers multihitting the crabs for shit to stabilise again. At which point they could delete every single wave with only minor damage to the lines because of the ranged attacks.
They would end up with 7 digit total damage numbers by the endgame. Like you just had the one turret in the game that solved these attacks and nothing else would come close, sans maybe mass-replicated minefields.
And even better solution was to get artillery range and never get an attack on Gleba again
