Feedback: Lethality

Out of the last several games I've played, and overwhelming majority of them look like the screenshot attached.

Riot - Your lethality changes are still causing major problems with game balance and normals have basically been reduced to "whomever has the most lethality champions wins."

I'm not saying the change needs to be reverted, however, the levels of base stats for champions need to be examined- this is a team of three champions building lethality exclusively. No defensive items, no survivability items, no utility items, straight lethality. It works because their damage scales out of control in the early game, and by the time the twenty minute mark rolls around they win teamfights by simply deleting champions. What is the benefit to building anything other than a lethality champion right now, with lethality as strong as it is?

In other words

What motivation do I have as a player to play anything other than a lethality champion right now?
