death dance passive should work like a zed ult.
when taking burst damage (more than a certain % of your health bar) from one or more abiltities simulataneously, it should store and pop all that damage at once 2 seconds later.
this would really guarantee, that marksmen will be able to get a couple more auto attacks or best case cram a heal in, but will eventually take the full amount of burst damage that they should have received from the start, instead of drain tanking it off.
also revert
to what it was and remove the damage reduction from 
i dont understand why marksmen are the only class that is allowed to break their own rules and itemize to negate their only weakness without any tradeoff whatsoever.
otherwise when were already going down this route, i expect a juggernaut item within the next couple of month that gives them ranged instant gapclosers with perfect stat combinations for them aswell. seems only fair.
why should marksmen be allowed to ingore burst, while other classes are shackled to their own counterplay?
and
swap stats but keep their passives? Are you fucking nuts? Give mages a universal item that any of them can and WILL build (because it's free fucking safety, why wouldn't they?) and leave tanks with less power to to deal with burst overall.
and
are really the only ones who get it. It is not as common of an item as people make it out to be. Graves is not even a marksmen ADC. He goes in the Jungler role far more often too.
to mitigate their kiting weakness. Mages have
and a decent amount of other health items to help mitigate their squishiness. Tanks have
to help deal with lack of damage in their kits. AD assassins have
to help deal with teams. Basically these are only examples of ways items help diminish the weaknesses of their class without major trade offs. Overall, I would also like to add what would the new passive of phantom dancer would be if you removed the damage reduction aspect of it as it would just become trash tier immediately without it.
and to follow up engages of your tank. its not a replacement for hard gap closers.
items that let them move faster. assassins have
. mages have
. fighters have
not to mention rages movement speed bonus only comes to effect when youre already in melee range of the enemy. it doesnt help you close the gap.
