Ashe's Passive could use a rework
So, after watching how a few champions had their abilities and passives reworked, I thought Ashe would be a good candidate for this. I mean, her passive is horrible if you want to score critical hits. Not only do you have to spend three seconds without attacking (which during a laning phase or a teamfight means you won't do anything), but you also have to wait until she reaches one hundred points of concentration for a single crit. Meanwhile, Caitlyn's passive allows her to stack a critical headshot every time she attacks, and even double if she hides in a bush, which means that for every critical hit of Ashe, Caitlyn already dealt ten headshots in a row without stopping.
So, I was thinking that maybe her passive could be changed a bit, kind of like how Garen starts kicking sooner as you elevel up, and maybe speed up the rate she stacks her concentration points. I'm a main ADC, but I barely play with her because my other ADCs are more "fun" to play. After all, only two of her abilities deal damage, while Jinx, Caitlyn, Tristana, Ezreal and Vayne deal damage or increase the power of their attacks and/or other abilities. I don't ask for a full rework, but maybe a revision to her passive so she can become better.
