Another one of these threads?
What I said in last thread: It's a Niche item that fulfills a very specific function and is perfectly viable in that function to counter certain characters. It's also quite cost efficient I believe, generally a pretty darn good item. The only reason nobody buys it is because it doesn't build into anything useful, it's not worth wasting an item slot on usually.
Buy it as a counter-pick item.
Hope that riot lets it build into something in the future. Don't get it every game.
Hey look, it's Emumu --
