Make it so that Akali doesn't get R2 if she doesn't hit R1
Make her R just go on cooldown if she doesn't hit an enemy. Decrease the width of R1 so she can't just clip an enemy and escape with R2. Give it a small windup similar to the length of Ezreal's blink.
It's good because it allows for skill expression for both Akali and the enemy player. It allows for her to have less of an oppressive engage range and gives the enemy more ways to counter Akali, they could flash away or zhonya. It punishes the Akali player for missing too. This would be a large change in higher elos because players there can better predict/react to when Akali is going to use R.
The only problem I see w/ this suggestion is how it benefits ranged enemies against Akali more than melee enemies, but currently the targeted R1 change on PBE makes her much more impactful top than mid so this change is a bit better, although not perfect.
