Is it me, or is the AS buff largely wasted
I can only think of Nami and Nunu who give one, but does anyone use it sparingly at best? I typically keep it up as Nunu because he can't Q an enemy, but the AS buff is never the first thing I use, and in Nami's case, it's third, or forth behind items.
I was thinking the buff might be better if it just allowed the next 3 attacks to have their AS improved, as opposed to falling off after X seconds. I was just looking to hear what other folks thought.
