@Riot New AD item fails to do its job

let me explain, you wanted a dfg like item for AD's that would help assassins dps down the front line to eliminate the possibility of another pure tank meta, which is fine. BUT, the problem with the item is the 2 seconds delay, you see in 2 seconds you will drop around 20% of the tanks Hp so the item wont do jack shit because hes still almost full health, while the squishie's on other hand will get dropped 100-0 from a full rotation like assassins are supposed to but with a 3 spell rotation (no ultimate) they usually survived at 10-15% hp, well with this they die from the item, making counterplay on assassins impossible (exept zhonyas or Qss, which gives magic resist), i think the problem would be solved if nightfall would deal dmg after 5 or 6 seconds, that way you have time to input dmg on the tank for the item to achieve its purpose while squishies die before that anyway.

would like to get your opinion about this, thanks :)
