Can we make turrets do damage based on what you do?
If you have AP, then the turret does 10% of your AP extra damage per hit. If you have bonus AD, then it does 5% of your bonus AD per hit. This is not to replace anything that exists currently, it's to add onto what we currently have. (That and return the turret shields.) "Do what you will with the scaling, they only exist for the concept."

gets ahead early, and he/she/it gets ambitious and dives bottom lane. This gives the "underdogs" a better chance of surviving.
