Would it be too much to ask for if we started with this?
Phantom dancer gets reworked and loses that dmg reduction.
Deaths dance option #1 = dmg delay reduced to 20%. No longer has physical omnivamp. Now heal for 20% of physical DMG dealt through spells. Has 10% life steal. This makes deaths dance more of an AD caster item and only somewhat useful for ADCs. Will favor fighters and assassins more.
Deaths dance option #2 = just nerf dmg delay to 20%, don't try to mess with anything else.
I personally would rather have ad "defensive" itemization needed before seriously spanking support items (not that I'm opposed to a potential support item nerf).
Ad defense options are bullshit, mostly for adcs, but a few champs like fiora and riven abuse them too hard as well.
I personally want to see a DD change favoring spells over autos (spells of course being defined as anything that triggers sheen).
