Changing the respawn timers to discourage bad play

Here's an idea. It's true that you can't fix stupid, but you can make stupid stare at a gray screen for more of the time.

Currently here is the formula for respawn timers, it is linear piece-wise and only based on champion level and game time. My idea is to make respawn timers longer in the early game, or base the respawn timer on stats such as team death counts. This would make it more punishing for idiots to die early game, but it would not discourage people from making calculated risks when they see an opportunity, because you can also punish the enemy for being idiots.

Just spitballing some ideas here. You could base it on the player with the most deaths on your team. (However, this could make griefers even more painful.) Or base it on repeated recent deaths. (Harder for an individual who is behind to come back.) Taking objectives decreases your death timers. (Other unforeseen consequences...) Since this is only theory at the moment I don't know what could happen. And perhaps there's more incentive to 5 man invade, or something else. Your thoughts.
