Instead of completely reworking Irelia, can we just change her 'e'?

TBH this is really the only thing about her kit that makes her unhealthy. She has a dash that resets on kill, healing, a small amount of true damage, and an ult that does negligible damage. Oh, and she also gets some free tenacity with her passive. Nothing too crazy here. But her stun lasts so long it's very difficult to play against. The stun lasts long enough that you're able to get a few extra auto attacks before it ends. So throughout the laning phase she'll simply e+auto attack a few times and back off. This process is repeated until you're weak enough for her to dash onto you and all in you. Anyways I think if we just reworked her stun she'd be perfectly fine.
