I want give you a suggestion of Ashe. About a more interest of her W.
I have a idea, I always think Ashe was so weak. And I want it will be stronger. I know that's impossible. But I still post this. Because I still have some different idea. In order to give a bonus prize. I think it can be give a buff on W. To give players gift if he use W killed more and more minions. Will give bonus gold and percent ability damage health regen. That's what I think. My main idea is to make W to so Technical(技巧性), playability, interest on using W to kill champion or minions. Or you can make if using W kill a champion will reset W CD and back ability cost mana. I don't know if someone like this, If there is please support me. I hope some advice.
