Can crit be reworked into ramping up DPS?
ADC as a class is meant to do sustained damage, and crits make AA more bursty. What if crit chance was reworked into ramping up AA damage over time/on-hit?
The general idea I had is that autoattacks can ramp up to 300% damage (probably needs tuning). But in order to reach that 300% damage, you need to AA. "Crit chance" (probably with a different name) would give you that much damage boost, up to that 300% cap. So
with 30% crit chance, with 100 AD, will do 100 on first AA, 130 on second, 160 on third, 190 on fourth, and all the way to 400 per AA on tenth AA.
(all numbers up to adjustments, ofc; 200% might be more than enough)
If this would make on-hit champions broken, maybe it can just be changed to over time in combat. But the idea is that instead of crits giving damage straight up, it should give damage over time, since that's what DPSing is all about anyway.
Some other changes that can go along with this:
: slows attack speed, or ramp up speed.
: reduced damage from crits, but only on the crit portion (using above example, the damage would be 100, 127, 154, 181 ... 370)
: not really sure what to do about this. This change focuses on DPS/AA carries, not AD casters. Mana refund could be adjusted fairly easily (probably based on how much crit damage you do), but not sure about CDR. CDR changing mid combat could be just confusing.
: increase the crit cap to 400%.
: MS also ramps up with crit stacks.
: no major change
: can ramp up crit at 50% effectiveness with other bolts, but can only crit on primary target
: no major change
would need some serious love after such a change, because he doesn't get to ramp it up...
But other than that, sure, that could do a lot for the game

: TBH he probably needs a full VGU. RNJesus critting you out of lane with 35% crit chance at Level 2 really isn't that fun.
: Probably would need buffs (sorry but just my opinion if this change went through) but not massive ones since he's already in line for some nerfs according to Ask Riot.
: I guess he would have to go more On-Hit, but he will probably need a little bit of compensation, but not a ton.
He's apparently getting a full VGU sometime down the line, but his AD build is already sub-optimal, and his AP is getting nerfed, so he will definitely need some help.
give 155 bonus ad and 80 crit stacks on top of ~100 base ad, making initial autos deal 255 damage but late autos deal 1275 damage. Killing them quickly or keeping their stacks down by stopping them from autoing is essential to the outcome of teamfights.

to name a few.
