User blog comment:Hidden Sniper/Mechanics that don't make sense to me - Part 1 Lifesteal/@comment-4922088-20130716224611

Lifesteal is the defensive stat hit by the MOST counters in game.

- Grevious Wounds

- Attack Speed Slows (this covers a lot more than just what these three words can say. )

- Armor/damage reduction

- Blind

- Stun or any cc that prevents auto-attacks

- Attack damage reducers

If anything the only thing about lifesteal that needs to be rebalanced is the fact that you can heal more off of a minion than it actually has health just by critting it. Even that though would need to be looked at closely because of how much it could buff poke since the ability to heal it back would be much harder.
