Burst is so insane right now that lifesteal doesn't even exist anymore...
Nobody even buys lifesteal because it's utterly useless in fights.
Off the top of my head, the ONLY viable sustain champs I can think of outside of Mundo/WW (who build tanky and don't actually build lifesteal) are ones with the ability to drop agro between fights like Swain (with zhonyas) and Vlad (also with zhonyas). Everybody else just builds tons of damage so they can 1shot more people. Heck, there's not even any point in building bruiser anymore, because you'll still get 1shot as long as the other guy went full armor pen and burst damage.
