I think matches need to pick up the pace towards the end of the match. Since mammet self destruct is kind of strong on towers and enemy base, I think if the amount of mammets spawned should increase as time goes on like in other MOBAs. But since players don't get stronger as time goes on like in other mobas, their HP should be reduced to stop there being so much time spent on mammets.

So say after 10 minutes, 2 mammets of each spawn each time with half health. After 15 minutes, 3 of each mammet spawns with 1/3rd health. But even with lower health, I think their damage to towers should stay the same.
