User blog comment:TheTobarMethod/HP Stacking, This Is An Issue/@comment-4022742-20130212152606

It makes it harder to counter (for AD) since they removed Bloodrazor in favor of BotRK. But where liandry's has bonus damage on MAX. HP, BotRK only does extra damage of current hp.

This makes health stacking and carries like Kog'Maw, Vayne and Varus quite unfair, since there is no way for other carries to be as effective against health stacking.

The only options I see is to either make health more expensive again, or to make BotRK equal to LT and create an AP equivelent for TBC.
