Remove Death's Dance
is just dumb.
Oh, you need an actual argument, can't forget about that since it's 2019. Well, in that case....it's an item that allows ANY champion in the game to receive almost 0 damage, assuming they can proc the sustain passive, which applies to.....all types of damage....meaning damaging anything with ANYTHING results in you actually being able to manage the damage-over-time passive.
For reference, Riven and Aatrox are the main offenders, like seriously, the moment they pick up this item they become nye-unkillable. Then you have Kat, Akali, Illaoi and ADCs as runners up, followed by everything else. However....just today I faced a Kha'zix that picked Death's Dance up as his first item, and he was quite literally unkillable until I had 4 items as Akali, and even then I needed my entire team to focus him down. Mind you, I built Morello's 2nd, so I had Grevious Wounds....
I used to think this item was cool and interesting, but after playing against it extensively as well as using it, it's simply not a fair nor healthy item. Remove this item from the game or change the damage-over-time passive to be far more volatile, forcing its user to hyper-sustain through it.
Side note: Gunblade should also be removed. As a Kat player I know from experience that an item like Gunblade should not exist as it provides far too much for its gold, especially on Kat, Akali and Kayle. Bring back Will of the Ancients, pleeeeease.
