thornmail does a LOT of damage when you build it on rammus

oh wait, that's just the W damage. thornmail isnt doing shit lol. if i want 100 armor, i'll buy it. but that's it. the passive component is useless now, and since so many items have life steal on them, adcs will be healing off all the damage thornmail does to them. i built thornmail on naut against a kalista. all she had was a botrk for life steal, and she still killed me in just 4 seconds and got out with over half health.
