Death timers need to go up faster so comebacks can happen
Right now if the enemy gets an early lead and takes an inhib, it doesn't matter if you then win the next 4 teamfights in a row fighting out of base. The enemy just slowly gets a lead from splitpushing while you deal with supers. If the death timers went up earlier, the team fighting from there base would have a chance to capitalize on a won teamfight, rather than the enemy practically being up almost as soon as the teamfight ends.
