Incidentally, Ravenous Hydra happens to be the single most common buy on Riven (built in 59% of games; comare that to to Bloodthirster's 43% purchase rate). That said, you did read that from a section that won't be in the final draft of the article, though the final edition will still recommend Hydra over Bloodthirster because it's a better item for Riven: the reasons stated still apply (waveclear and burst damage are superior, hands-down).
