Well, I actually have flat AD, and not ArPen, as I don't have a lot of runes yet. I thought, however, that ArPen was considered standard on champions like Riven.

Still, as you can see, there is a BIG difference in damage between Bloodthirster and Last Whisper, mostly when you have high scalings, like Riven (hell, her scalings get even better with her ult, as that counts as bonus AD).

I do agree, however, that Last Whisper is a good item.

Last, AD instead of ArPen only means that your bonus damage will get increased and your base damage will be decreased -> Bloodthirster gets even better as first item.
