Removal of "Executioner's Calling"

Here's the thing. Imagine this situation. You are an Aatrox playing top lane, Warlord's Bloodlust, got a 1 kill lead from your opponent, Jayce. Then, Jayce goes back to his base, and buys an item, Executioner's Calling , for 800 gold. Whenever you deal physical damage, this item triggers "grievious wounds" on your opponent, reducing healing by 50%. Therefore, your warlord's bloodlust is completely useless, so is Blood Thirst, your W. Then, the enemy Jayce tells his fellow teammates, Master Yi, Ezreal, and Yasuo, to buy this item, Executioner's Calling aswell. When you, the allied Aatrox, try to trade with any of these carefully selected people, you will fail, since your whole kit is destroyed. All of your abilities drain health, and that's the idea of Aatrox. I think that, for 800 gold, you shouldn't be able to disable a champion, like aatrox, or whoever the champion might be in other cases.
