Stormraider's Surge and Ashe
Riot please take another look at Stormraider's Surge. This is a mastery that could make Ashe utterly useless against any champion with damage. As long as during a fight a champion with the mastery can get 30% of anyone's HP down, they'll become immune to Ashe's passive, removing her bonus damage and making her form of crit nonexistent.
As we all know, ADCs need crit damage to be the late game carries for their team, and Ashe's is shown through her passive. If the change goes through, her crit damage could be nullified and she would be rendered useless.
