Okay look, so you made them smaller in the attempt to keep ranged from being able to shoot as accurately at longer ranges (too small to see, they can't adjust their aim). Well at least that's my theory as to why they are smaller than they used to be. Problem is, as with all nerfs like that, they adjusted and can hit you just fine.
So why do I call it a buff?
Well if ranged still know where their aim is going and the missiles are a LOT harder to see, it is a buff to ranged because it is much more difficult for melee to see the damned things and dodge. Agility is only useful if you can see what is coming. Make the missiles as big as it takes for people to see them incoming in time to dodge.
