Why does Gunblade offer more sustain than Death's Dance?
Both items
have the same kind of healing mechanic, yet Gunblade...
Heals you for 15% of all Damage dealt, including Physical, Magic, and True Damage.
But Death's Dance only heals you for just the Physical Damage you deal, why do both items differentiate from each other so much in the healing aspect?
I suspect it could be something to do that Death's Dance has the damage reducement Passive, which causes you to take delayed Bleed damage as True Damage (based on LoLWiki).
