Why is Keane building FH and not IBG?
Genuine question, to my Silver eyes it seems like IBG would be better because it gives a Sheen proc and AP, two things FH doesn't have.
I try to learn all I can from watching LCS, but this is something I don't quite get.

, if they are talking about the quarter finals vs Impulse.
and tank
. When building CDR they have low cooldowns and high mana costs, the frosty sheen proc compliments their CC and IBG gives them decent tank stats without wasting the 30 AP the item provides. Keep in mind that Frozen Mallet and IBG slows don't stack, so keep that in mind if you were thinking of building them both. IBG is a situational item that can provide more peel or allow your team to catch up to a target you have in AA range while providing a moderate boost in damage. FH is a better defensive item that is low cost and gives great stats.
