Big outplay wow, 3 auto attack!
Look at my outplayed as an ADC, just 3 AA on that Lux. She even Zhonya, ya zhonya literally saved her life.
Whats the counterplay to auto attack as a squishy champion?
Just don't get in her AA range, yea right but what if I'm melee?
to click out of your root or stuns..... well that gap closers sucks. I understand what you are staying but its to the point not with life steal, resist, rez armor and being able to click out of CC has seem to get rid of there counters. While in theory your are correct but Mages don't have the "select" of item to off set there weakness. See
immunes them but they can't move. Its like making a knock back item for mages. Once you get to them they can knock you back 900 range with a 900 range cast. That is the issue. AD and ADC have things that make up for their weakness as champs. Mages have to have trade offs. hp or ap, resist or ap. AD items have don't get low ad amounts because of life steal or click out.

The reason that ADCs do a ton of damage with their autos is simply to balance the game. They have to get into auto range to do any damage, and mages can often melt entire teams if not multiple people, which most adc's can't do.
