Adding a "dodge" mecanic for autoattacks?

I know it would be hard to implement but wouldn't that be a decent counter to the ridiculous safety/damage ADCs have now? There used to be a time where it was the recognized as the hardest and most mechanically intensive position but now who cares about positioning and kiting with all the stuff they have to survive.

How about adding a dodge mechanic to certain tank items? Maybe in the form of %chance to dodge auto attacks or items with actives. Of course it would only be for a short period of time but it could counter critical strike nuking DPS that we currently have.

Maybe make it so when you dodge something you deal less damage so only tanks would really want to build it. Jax and Teemo with more chance to dodge autos would be cancerous.

Just a random idea I thought of. I know it would be hard to balance/implement but what do you guys think?
