Maybe make it a weapon that has remnants of the power to curse. If it takes effect, AND you kill them with it, (Make it a weaker weapon also.) then they are cursed for the next 30 minutes or something like that. Would work better.
I'm totally against it seeing as how curse is an instant kill. At least with poison, bleed, and toxic you can keep fighting back. But, heaven forbid they do, I'll only be ok with it if the build up is slow, and it's on a great hammer that requires 50str.

I'd like to see it, but it needs to be done in a somwhat non-abusable manner. Perhaps something similar to the Dark Hand, a grab attack that has a fairly large and obvious tell. Maybe make it such that you must "kill" with it rather than simply building curse up, that way, you still need to PvP for it to be used.
If you are just pvping in the burg and lose to it, it's just an annoyance to have to take one more step to remove a curse before you get back to dueling. There is no consequence since you are really not leaving the area to progress in the game.
It's a good idea for those people you impede in progress
