Purchasing two items that specialize in kite and lifesteal respectively means more gold and less damage during midgame. More gold to be able to afford two items and less damage because you can't purchase a third damaging item as well, whereas you could have a kite/lifesteal hybrid AND an actual damaging item and be more effective in teamfights. Not to mention the fact that we already have a dedicated lifesteal item as it is - bloodthirster.
What is the point in survivability as an ADC if you're totally useless until lategame because all your items are designed to do is keep you alive and not actually deal damage?
Maybe some specific examples would help, then.
Blade of the Ruined King
Builds from:
+
+
Grants: Crit, AD, Lifesteal, AND
UNIQUE active: Steals HP and movespeed
And one of the following unique passives:
Your critical strikes heal you for (percentage) of your bonus attack damage
OR
Your critical strikes grant you (percentage) movespeed for two seconds
Kitae's Bloodrazor
Builds from:
+
Grants: Attack speed, AD, Lifesteal, ArPen, AND
UNIQUE passive: Your basic attacks deal (percentage) of the target's max HP in physical damage OnHit
UNIQUE passive: You heal for (percentage) of the OnHit damage you deal
There we go. One offensive item for lifesteal and kiting, one offensive item for lifesteal and OnHit. Straight forward enough?
