If you get an ace when the inner turrets are still standing and you have a wave pushed up, past 25 minutes you can just end the game from there. I get you're trying to lower game times, but making the most important objectives in the game worthless isn't a good design choice. It completely sucks that people can push past four towers in less than 40 seconds because they hit like wet noodles. They were fine before, why can't we just have the lasers back?
BTW just my opinion, it's entirely possible I'm wrong about this.
