Death Timers and Games That Do Not End

I don't know how everyone else feels about the new death timers but it feels like there are some games that should just end, that just don't. And what I've experienced is long drawn out games where even spite of being aced one team can still come back late game. Past 40 mins. I think death timers are too short. Frankly after getting one or two man advantage objectives are harder to kill, leads to too long games, and the mid game feels meaningless. Thoughts?
