Lifesteal getting nerfed would make heal champs a must, at least in bot lane. You can't survive a poke lane in bot whithout lifesteal, so take that into consideration. Good luck vs Ez+Sona botlane, anyone without as much poke. You are getting destroyed because lifesteal OP and needs nerfs.

Crit is also not luck based. It is % chance based. You can get fairly easily to a high % chance, which combined with high attack speed makes that ~60% much much higher. It also is the only way ADCs can survive prolonged teamfights with their nonexistant defenses.

And also, lifesteal is borderlines useless against burst champions or grievous wounds. Which ignite (second most used summoner by both mids and tops) provides. So no, lifesteal is fine, and as said, needs damage behind to be actually useful. So if they are lifestealing more than you are dealing, you are underfed, they are fed or both. Or you are not four man focusing the ADC.

Lifesteal is fine, IMO.
