Can we punish people more dying and reward less for getting kills?

It feels like this game (at least in soloqueue) is just becoming a slaughterfest with people just picking assassins and other champions with high kill potential at each other over and over again trying to rack up kills no matter how many times they die in the process.

Riot since you're trying to place so much emphasis on "strategy" and stuff why don't you try making killing someone more about the "what can I do with the time in which there are only 4 enemies on the map" and less the "sweet now i can build moar glasscannon to pad my KDA and kill moar people".

It's ok to die in lane. You get outplayed, you get ganked, maybe you got unlucky and tryndamere critted you 4 times in a row (seriously fuck that champion). But what's not okay is trying to redeem yourself or some bullshit and continuously trying to fight your lane opponent when behind. This seriously annoys me to no end in ranked. Please just literally sit under tower and grab what cs you can, or if your opponent is freezing then go roam. Just don't try and fight him again and again until maybe you get so far behind they try and tower dive you screw up and you get a kill. Not worth (seriously it's not worth don't you even dare think of saying wurf in all chat).

And I think the game itself cultures this mentality of not feeling bad about dying since you're only indirectly punished for it. You know maybe that's why the game is popular in the first place since it doesn't feel particularly punishing for making mistakes, but I digress. Something needs to be done about this.

I don't care whether it takes making people lose a little gold for dying, increasing death timers, or anything else but SOMETHING needs to be done about this gameplay that fosters chasing potential kills at the definite cost of your life. There's calculated risks, and then there's just a Riven smashing buttons furiously in hopes of killing something (I swear everytime I see a Riven she either gets or gives first blood).

I know everyones wound up about Riots balance team right now (I am too) but I feel like this a major problem with one of the games fundamentals that needs to be addressed.

tl;dr this game isn't CoD it shouldn't be all about getting kills
