Duskblade
Duskblade might actually be worse than DFG.
DFG was at least equal to everyone. Duskblade is awful to anyone that doesnt build armor and hp.
DFG also required you using an ACTIVE then hitting X spells after (some obv offenders like viegar and ahri but I mean shit happens)
Duskblade, requires you to not be seen for 1 second (Has a passive that literally helps itself.) So not only does the item have high damage for a first item. But it gives vision denial :D
At least DFG, you saw that you were going to die if you walked that way towards the enemy.
With Duskblade, you don't even know where you are going to die from because. Vision denial
