No, the ability was originally intended to quickly generate shield with a low amount of damage behind it. With the added slow, it has even more uses. Beeing uncounterable is now a nonfactor, as the ability shouldn't be that strong anway, compared to Q, W, R. Every champion needs 1 ability that is less powerfull to open him more unique strong ways of dealing damage.
