Glad to see you working so much on the balance!
I think that the more you have to do in any level the more the time limit will feel too short. I do think that quick runs are good, but they should allow you to do many things. At least in my runs I was okay as long as I didn't fight anyone, was that your intention? If I fought anyone it was too little time.
Hope that helps you with the balance, and I do agree that I may be an outlier ;-P
Thanks for giving more detail - definitely sounds like I need to turn the health down a bit then!
I originally envisioned hopping in, opening some crates, killing a few enemies, and then at that point needing to make the decision to extract early or push your luck to get some more loot but run close to the time
So tuning down the enemy health a bit should skew it in the players favor a bit more to squeeze in a couple more kills before having to leave (hopefully)!
