By that logic you could argue that we should also get rid of the PPU Rez. Death should have a penalty and a rez negates that penalty. I do understand what you mean though, drugs and drug flash are crazy right now in game.
Here's an idea make it an APU spell, and make it's casting time like half that of a rez, so it give utility to the apu without making it too easy to get out of drugflash.
Although if you want to solve the crazy drug and drugflash problem there are way more things they could do. Make it so you can only take one drug at a time, make it so re-drugging does not cure drugflash. I do feel DF should be lifted upon death though.
