Riot, if you want big burst and one shots in LoL to be the norm, reduce he death timers.
I recently started playing Overwatch, and in that game, burst damage and getting one shot as soon as you step out of spawn are the norm. And i don't mind it. Why? Because i don't spend 40 to 60 seconds dead. I spend 10 seconds dead, and in that time i get to fully see how my enemy killed me and what mistake did i made. This is also a time to mention that LoL's death recap is a caveman stone tablet compared to Overwatch's death recap.
My point is, general frustration in this game comes from the fact that players spend more time dead than alive. The death timers have stayed the same since the times when the damage in the game wasn't as high and oneshots were a rare event. But now that i can spend 40 seconds dead, spend 20 second going back to lane, and then 20 seconds alive before Rengar jumps out and deletes me, and then 40 seconds dead again, it's just a flawed gaame design.
Riot, you need to decide if this game will stay a strategical slow paced battle arena, or a fast paced survival horror battle royale. Maing a weird hybrid and trying to cater to two different palyerbases is a flawed decision.
