Lifesteal without damage behind it is nothing. You can have 100% lifesteal and 200 damage but you will lack a lot of other stats.

Sion has the highest lifesteal in the game yet everyone considers him as unviable pile of you-know-what.

Also, lifesteal can be countered by many items. Everything with grievous wounds can do that. Ignite also does the job.

Also, lifesteal is not calculated before dealing damage, it is calculated after. That means you will heal for less if you hit a tank, than ad carry for example.That is why Tryndamere can't beat Rammus even if he runs lifesteal.
