You also lose damage on your primary target in order to get rather miniscule damage on more people. The attack speed is nice, but building around kog's shred on his W as an adc just leaves you weaker in most cases.

Hows my post relate to Vayne? Well..erm...

Single target burst/dps that just outright kills someone is often more valuable than small AoE damages due to the fact that targets that take slight damage can still meaningfully contribute to the fight, while quickly eliminating a single target completely takes them out of it. Kog'maw is one of the few that can compete with Vayne's tank melting, and it's more useful for both of them to quickly take out the main tank/bruiser than to try and kill both at once less efficiently.

There, now that's not completely off topic.
