Death timer's need more "balance"

Ok so i just finished a ranked game. im not upset that we lost at all (im not that kind of person). How ever i seriously doubt that the games Death timers are correctly giving the right times. twice we aced the enemy team and by the end of the fight or right when we would start pushing 5 seconds after , 2-3 of them would be back up guarding. While on the other hand we where aced once. and we all had death timers ranging from 45-55 seconds.

I am not stupid i know that the time increases though the game. but both times we aced them it was around 44 min after they baroned. when they aced us , it was only 5 min. after that.
