User blog comment:Hidden Sniper/Mechanics that don't make sense to me - Part 1 Lifesteal/@comment-6281755-20130717121911

This isnt dota, you cant buy damage and be tanky at the same time, thats why we need lifesteal. Lifesteal is the thing that keeps people alive in teamfights, and it lowers the learning curve for new players a lot.

Have you ever played Akali, Jax or Zed, and in teamfights gone for the enemy ADC when you had the chance, if not, do so and come back to keep reading.

ok, back?

Can you understand how squishy ADCs are, without lifesteal they couldnt teamfight at all, because, any poke and they would be rendered useless. Most melee ad champs get good ratios or something to make up the fact that they have to get close to do damage, for example gapclosers, tankyness skills, or cc. Take any adc and think how they would be if they were melee.

Ok done?

Pretty useless huh? ADCs are given few things to be usefull, lategame damage, some minor peel and some lucky few have gapclosers/escapes, take those things away, and boom, bruiser meta all over again.
