An idea that will probably get downvoted
So
has a W that makes the player think if they should use it to buff an ally or disable an enemy which I think is really cool since not many abilities have multiple functions. However her E doesn't have the same concept since all her E does on an enemy is damage them and reveal them.
Since her main job is to protect allies by stopping assassins or fighters who are usually mobile, I felt it would be cool if her E grounded the enemy target for around 1.5 to 2 seconds. Plus I feel she needs a buff anyway.
