Who thought 60% armor piecing was a good idea?

So Gangplank's W is an AoE that ignores 60% (PBE 50%, whooooo) of the target's armor. And every barrel that explodes ignores that amount.

Who thought that was a good idea? Seriously.

The range at which he can lay them down, and the connection range at which he can successively detonate kegs is oppressive. I saw a GP consistantly blow his barrels up when the distance between them was greater than the AoE of the individual barrels themselves. How does _that _work?

Yeah, I get that there is a slight nerf coming to them, but it's just that - a slight nerf. Either the armor piercing needs to get cut in half, or the range at which he can successively detonate kegs needs to come down, or the armor piecing nature only applies to the first keg, or SOMETHING.

When a tanky Mundo loses almost a 1,000 GP to a GP barrel, something is wrong.
