We were wondering the same thing, because the units and buildings suggest that there should be a pollution cost to it, but you can build as many buildings as you want and easily get like a hundred spawners in ±30 minutes, and then just continuously attack the players.
So is there anyway to make it more playable for the characters?
Or to let the spawners just cost more biters the more spawners you have, for example the sixth spawner cost like 5 more, the 8th another 5 more etc. ,
Or anyway to make the buildings atleast cost pollution?
