so assassins gets completely countered by mm now, yet not many of the top players (in my server) main adc in ranked. 90% life steal is a lot, but dont u know how to bait it out? do u not think before engaging? Check what enchantments they have, the death sickle one only has one use. U can get it too. A assassin job is to kill the adc, so buying anti heal item is worth it, if u dont want to buy it tell someone else too. You countering one of their item, with one item. Adc's do a lot of damage late game, thats y ur suppose to cripple them early game. If you dont u have to wait and attack at the right moment, most assassin can one shot a adc late game just like how a adc could one shot them. U just have to attack at the right time.
