This was seriously discussed on the official forums some time ago. Unlike lets say Dota, LoL doesn't have any "chance" mechanics left in the game. Crits are the only one left. Adding dougue again won't solve it.

Thats one point here is another. You know thr problem with ADCs? Well their absurdly overpowering late game makes then distord the entire game. Most of adc are supposed to melt tanks, and they can only make sure they do by multipliing their damage with crits. The problem is, that Ashe (lets say) could just hit a perfect iceberg upon (Lets say) Katarina. Ashe then butchers katarina with 3-4 crits ( ADCs get this by late game really easy)  in a row and her outrageous AS. Ashe didn't got that crit chance & damage to murder kata, she may not realize it, but she got so she can kill tanks. A tank should be dealing with kata ot another assassin, its just wierd to see an Assassin getting murdered by the class they counter. Sure a more proper engage by kata would have killed Ashe, but ashe dealing more damag and high cd nukes with each attack is stupid. And lets not talk about other Draven

However, ADCs have to build the crit to kill tanks late. A tank can't take fire from ann late ADC for more than ~7(4 vs vayne, 5 vs draven) seconds before exploting. And dats good, ADC are supposed to do dat. The issue is dat all the other classes suffer a hell lot from this. AP janna can get her stupid huge shields ~800 pierced by a single good infinitycrit. Fighter wukong won't last more than 5 seconds under the full fire ( for example if he is retreating) of even Graves who is known to fall off.

Someone mentioned giving staright % AA increace instead of crit, and remove the random chance. This however does not solve the problem of the damage of the ADC distorting the late game, it just keep it the same.

And yes, any assasin can OHKO an ADC, but if such adc has a half decent support or a realy caring CC top/jungle she/he will just murder every other class. IMO full teams ( even mages end up doing it)  shouldn't be protecting a single champ. All clases should stay very relevant late, and on the same vein none class should be overly relevant early as it happens with some fighters right now, but thats another topic. On a final note, ADCs should'nt be the only ones allowed to murder nonstoppinlgy turrets

ADCs have to kill tanks. And we want to get rid of random mechanics. no idea what could we put in the place. Maybe removing crits all together and adding high armor pen, but VERY carefully itemised so that AD assassin don't get it. Like, if the Pen is exclusive to AS items for example. Thats a rather poor solutions but I can't think of much right now. I'd like to hear some other suggestings to get rid of the crits, and making the late ADC less aniquilating
