Dead timers

I want to discuss this little thing that has been bugging me since season 6.

I dont think is that good of an idea to have like 50 seconds dead in 30 mins of game.

Before, you had to be smart, maybe you had a small amount of time to understand where you had to go after a teamfight to make it worth it. Now, you have all the time in the world. If a team wins a teamfight at 20 mins, they have around 30 seconds i think to take objectives, farm, enemy jungle camps, ward, etc.

I understand if you say that the meta is around snowballing, but again, i think dead timers are way too long. One or two people getting caught at 20 mins can cost 2 turrets from same lane, or baron, or dragon and turrets, or taking control of the game.

TL;DR: I understand if you want to make it easier to push advantages from mid game kills, but dead timers make it very easy. Please, balance in the next pacthes!!

Sincerely,

Nacho.

Edit: Not sure if "Gameplay" is the correct board to post this in, but i wasnt sure.
