Lifesteal makes many champions unkillable and completely nullifies poke type champions that have to chip away small amounts of their enemies at a time.
Certain champion becomes downright overpowered with lifesteal. Some obviouse examples are 
and more.
in particular can solo the Baron with only four items. FOUR!!! That's so broken.
They got rid of spell vamp, now the logical next step is to get rid of lifesteal as well.
Have you tried grevious wounds?
Overpowered yet most of these champs dont have high winrate and yasuo and fiora are two of the champs with the highest skill requirement to play effectively.
No lifesteal means any champ that isnt poke heavy is immediately unusable
It's part of the rock paper scissors part of this game. Sustain>poke>engage>sustain. And they didn't get rid of spell vamp, they just took away its name, one of its items, and slapped it into your rune page.
Bring back true spellvamp
lifesteal is op?...really?..... [zombie-brand-facepalm]
