I've done Brutalizer + LW early. It's strong, especially if you already have flat ArPen from runes.

The Brut -> TBC upgrade only offers the passive, +25 AD, and +200 health for Riven. Last Whisper penetrates more Armor more quickly (although it's a selfish penetrate), and has +15 more net AD over the TBC upgrade, for only ~637g more. Worse for duels or small-scale battles, but better for blowing up an MVP as quickly as possible.

Against a carry with ~90 modified Armor, a 21/9/0 Riven with ArPen Marks and LW + Brutalizer is basically ignoring almost 63 Armor. This is a super-squishy Riven build though.
