There is one way to deal with Deaths Dance which wont affect it's intended users

You see the item screams AD caster

Many of those AD casters also use aoe abilities, but the item is only 1/3 effective on those

Reduce healing to 5% and make it 100% effective on AOE Or you could reduce its healing to 10% and make it more effective on aoe like 50%

You see that would make the item less effective for Single target damage, but not less effective for aoe damage

It is an overall nerf but the item could use a small nerf anyway

Alternatively the healing part could be removed with a buff to the bleed part 0% vamp 50% bleed, over 2,5 seconds instead of 3 Now it will be a real effective anti burst option but if you want to prevent your death you are going to need other ways to deal with the bleed damage and you will need to deal with it a bit quicker too.

Right now it's too good of an all round item with plenty of damage, pretty decent defensive tool, and a lot of sustain for bot single and area damage and some cdr to boot.
