Differentiation of turrets could add some spice to the game.

Why not make each tier of turrets distinctive from one another? On the surface this might seem like a pointless idea, but before outright dismissing the idea think about the upsides. One big upside is that it will always be easier to balance 11 turrets than 100+ champs and items. Another upside is that if nerfs are required there are no turret mains out there.

For example:

Make outer turrets deal more damage based on the amount of defenders. Turret dives are good for the game, but they are too easy to pull off in comparison to the potential rewards. If only one person is defending an outer turret it should hit harder. The damage the turret does should be reduced for each additional defender with a TP in the vicinity counting as a defender upon cast not completion.

Inner turrets should do something that maybe provides utility like have an aura that gives defenders bonus tenacity or a brief speed boost. The damage on inner turrets should maybe be lowered to compensate for the aura.

Inhib turrets already have regen so that is already something distinctive.

Adding a variety of turret options could be used as an additional balancing lever or as a means to just spice up the game. If you wanted to get really crazy there could even be turret package templates available in champ select?

Please share your ideas for potential turret attributes that might be cool to see in game.
