Make Base turrets great again!

In the light of just recent Riot post about pre-season:

I'd like to suggest a tweak to macro game. We all know how low damage and not punishing Inhib and Nexus turrets became this season. I mean late game even marksmen could walk up and walk out of turret range just getting some tickling instead of pulsing 300+AD warning shots that were sometimes present. I suggest that Riot tweaks turrets to be on par with Season 4 turrets, where we had one of the most legendary games ever played, mostly because macro game (and numbers) were just right. https://www.youtube.com/watch?v=NlRfO1dObeQ

As a compensation, they could even remove the Backdoor bonus stats that they are now having. I believe they also didn't even have these bonuses back then.
