Riot would you consider giving Ezreal his debuff back?

So, a long time ago Ezreal's 'w' used to reduce his enemies attack speed. But this was considered too strong and removed completely. It makes sense to bring it back. When used on allies it increased their attack speed, so it only makes sense that it would have the opposite effect on enemies. It also gives Ezreal some extra defense against late game adc's when he starts to fall off. Ezreal's 'w' is already a terrible ability as it is. It does barely any damage and the mana cost is way too high (like almost everything else in his kit besides his 'q').
