Gnar's boomerang needs a nerf

It is beyond me how this skill made it through testing... A reducible cooldown on a manaless ability with absurd range AND a slow... I dread top lane every time I see a Gnar because I know Im going to get poked to death by this ability if I`m a melee. Melee champs like Malph or Gangplank are a headache to top with because of that one skill. Get rid of the cooldown reduction for catching the boomerang. He already has a free escape with his leap but pile unlimited poke on top of that? It's a bit much. What do you guys think?I'm fine with every other part of Gnar but the boomerang, It's just to much.
