Is Last Whisper really worth it? I ask because its benefits severely diminish after his W's 50 ArPen is calculated, and in some (if not most) case even a single Brutalizer would give you more ArPen than Last Whisper. Let me explain,

I'd imagine you'll be targeting squishies (anti-squishy is his primary role) and more than likely, they won't be rocking 100+ armor. I'm also assuming you went full ArPen red runes (not including quints) and grabbed max Sunder from the offense tree for a total of 21 base ArPen. With W activated, that's 71 ArPen. Let's say, for example, you do target a 100 armor squishy; that's (100 - 71) a 29 armor target. Last Whisper will give you (40%) 11.6 ArPen from that. Brutalizer? A flat 15, which is more than Last Whisper even on a target with a 100 armor and I don't see many squishies getting that much armor (more like 60-90, at best).

I do give Last Whisper it's credit when your W is on cool-down since it'll give you constant 40% ArPen on all auto-attacks. To which I'll ask another question, wouldn't it be worth shelling out extra gold for a Black Cleaver? Even without using W's 50 ArPen, if you're attacking a 100 Armor target with just a base 21 ArPen (from ArPen red runes and Sunder mastery) you're left with a 79 armor target. Last Cleaver, 79*(.40) = 31.6 ArPen. Black Cleaver pretty much matches this in two strikes, and on the third exceeds Last Whisper's ArPen by nearly 15.

I'm saying LW is useless, as I see it's useful to have constant ArPen no matter what, even if your W is on cooldown. But, just wanted to point some things out for consideration.
