Remove DuskBlade of Draktharr just like you removed Death Fire Grasp

It cause a balance mess just like Death fire grasp caused on mage back then. Too good to not take on multiple champion and removed the actual counterplay on Zed, Rengar, Kha'Zhix and many more assassin. At least on Death Fire Grasp, the item had an internal cooldown to refrain the multiple kill... wait... Duskblade have no cooldown so you can rinse and repeat over and over again... When will Riot do a move already? Toning down the damage won't solve anything... it just make less damage on 1 time use... but nowaday, assassin goes in multiple kill and always have damage to back them up, even if they miss their whole combo.. and if it wasn't enought, Dark Harvest provide the extra boost they lost from duskblade damage nerf... It wasn't fun to get one shot by Rengar back then and it's still not fun, or any other duskblade abusers for that matter... I say remove it entirely and create something else more healthy.. or add an internal cooldown of like 30 second so you actually have to plan your assassination instead of running free as soon your ability are off cooldown and assassinate not 1, not 2 but 3 to 5 person.. because yes, thanks to duskblade assassins can pentakill... It's time this item leave League of Legends.
