Talon zed and khazix mid with hexdrinker

Does anyone besides me see hexdrinker and maw as a Problem. The amount of stats it gives is insane. Specially because it gives Armor penatration. Why is an item giving Armor pen and magic resist and damage and lifesteal and attack speed and a sheild. The problem isn't that this item exists. The problem is that it isn't a situational item. It's core for any assassin because of the armor pen. It's also probably the best assassin item because it gives you less risk when you engage. Riot we can clearly see that you favor zed.
