New Q is harsh on his jungle clear, I don't see why it can't have the old effect in the jungle (hit through all monsters and not just the first it hits). Although the new Q is creative.. It's not really _functional_ in teamfights either. It takes way too much focus to properly use. It's a cool concept but its payout is pretty mediocre.
Also I do not like the high pitched voice when health is low, it ruins the "immersion" of playing the character. Is our champion of choice supposed to be laughing stock whenever we're low HP? Don't really like it
Haven't used the ult enough yet to give a proper opinion
