Although I am instantly turned off by the phrase "have to" with builds, I thik Nosh is correct in saying yommu's attack speed buff is doubled when you w (it doubles your current atk spd and doubles your cap). I would say that against a tankier support in bot and against a fighter adc (leona/graves, for example) and with scarier bruisers in the jungle and top lane it could be the situational item that wins you mid game. Any adc scales well with armor penetration if the enemy team is building armor. To be an effective adc the important building principle is building appropriately for whom you're going up against. If they're not building armor, you probably wont need yommus.
