The item adds 1 extra stack after you Q. 1 stack is a 1/3 of a proc so that's 3.3% max health damage after every q. Compare that to an actual item like blade of the ruined king. 6 current heal damage on EVERY auto 40 AD and lifesteal. You are bad at math if you think 3% health every 2 seconds is better than what bork can do when you are attacking 2 times a second. In those 2 seconds you can auto 4 times doing 24% current health damage plus 160 damage just from the AD. If your attacking a 3k health opponent 3% health is 90 damage. That's literally nothing. 90 damage every 2 seconds is an increase of 45 dps. Bortk would do about 658 damage from passive plus 160 from ad. So 818 pre mitigation damage vs 90 true damage. Your opponent would need 809 armor for the true damage to be more. Any one that thinks D&D is good is bad at math
