endless modes with dog days like hotfix

[bananaphantom]

I wonder how endless modes would play out if they had a similar change to the dog days hotfix, but instead of extra pearls kills reduced the time of a round (somewhat similar to how defense works but more deliberate).

So like with eso, if you were to hit 100% efficiency for a long enough duration, the round would automatically end, going to the next. Or in survival the rate the time goes up increases based on the amount of kills at a given moment. Or in excavation feeding the drill extra energy reduces the time it takes for it to finish, ect ect. I really like arbitrations but I'm for the first half hour I'm not really doing that much, and I think it would be neat if I could speed it up to my level of difficultly.
