What Riot can do to finally break out of the "ADC always" meta

Morde bot will be a gimmick, but ultimately not be preferred for one particular reason.

Basically ADC's are essential to winning a game of league for one particular reason - killing turrets.

Sure, they also apply damage in teamfights, but with the sheer amount of champions and tactics available, reliable damage output for a team isn't entirely hinged on the ADC.

We need ADC's to win the game because AP and melee have a difficult time destroying structures. Since turrets are already too weak, we wouldn't want to change that, and that would still leave ADC's as the best option for destroying them.

Here is what i would propose. An item who's active ability damages structures from range.

This of course would take some careful balancing. I imagine it would have to give minimal stats (if any) with a very particular damage and cd profile, but i think it could be balanced. The item would need some very particular drawbacks and i think would be limited to one per team (possibly even barring teams from purchasing the item if they have a marksman present). The entire purpose would be to give teams a balanced option for destroying structures without having an ADC, but would be comparable to an ADC's ability.

This would allow teams to be able to actually win the game if they were able to be successful without an ADC. We could see the emergence of all sorts of different bot lane combos, which would ripple through every other role. If done right (as in, not just simply replacing adc's with an item) this could create the kind of diversity people love to play and watch.
