The main reason ADCs are picking up BotRK, is because it not only counters health stackers, but also provides lifesteal and percent lifesteal.

To the anon above me: it actually doesn't give more lifesteal than Bloodthirster, this is why you still see ADCs pick up BT first.

It deals 5% of the enemy's current health, not max. And heals for half, so you're healing for 2.5% of the enemy's current health. With your idea of 1.1K health, you're doing only 5% of that through the item, which is about... 55 damage through the item against a fully healed enemy. And being healed for 27 or 28 health.

A fully stacked BT is 100 damage (with 20% lifesteal), against an enemy with 3K health, with a BotRK, you're dealing about 150 at full enemy health (with 75 health return), that is not double, you are, however, healing more with it than a fully stacked BT. A BT is more reliable than BotRK, because it deals the same amount of damage against the target, where as a BotRK, will not.

A fairly good ADC build will have both, however.
