What I suggest from DD would heal more than the bloodthirster with basic attacks... Not only that it affects all physical damage the user deals. Vayne have great synergy with DD, I have tested this already on her.

Champions like vlad "abused" it due to the fact that he have innate SV, this would also apply to veigar (with AP stacks), Morgana (Passive would stack), Ahri (passive stack), Mordekaiser (does sap a lot of life on tanks with his ult), Malzahar (E and ult), Akali (passive), Annie (Insane burst), and others that can burst or have abilities that already heal them.
