Turrets & How to Fix Them...

Lets get the obvious out of the way first...turrets are weak. Now that we can all agree on that how do we fix them?

A couple of my ideas:

⚫ Replace SR towers with TT Nexus turrets. In case you don't know, those turrets are scary as hell. Now obviously some tweaking would be required, or not, personally I'd like people to be afraid of my turret. ⚫ What if supports had an item that could protect turrets? Invulnerability, damage buff, whatever.
⚫ What if towers gain power/resistances depending on the number of towers you have up. In other words, the more towers you destroy, the harder the other towers are to take down.

Those are just some unconventional examples of mine, what's yours?
