My thought is that you must be playing a character who's getting banished places, and getting voodoo'd. What a surprise to see you wanting them nerfed
.
Ribbing aside, I agree that bounty NPCs should probably be off the law system like Trib members are, but then again, you can get reported for killing Trib members, so it looks like I just talked myself into thinking it's good to keep them on. I am firmly in the don't do the crime if you can't do the time camp.
Voodoo I've always thought to be poor sportsmanship, but, a sprite in a religion is the last char that should be dying to it ever. With minimal effort you can have protection up all the time, with medium effort you can have protection and sanc up all the time, and with high effort you can have protection, sanc, and shield up most of the time. Added to your sprite MP, you will not be killable with voodoo unless you have built for asthmatic CON, which seems like a player choice. It is not as overpowered as people make it seem - it is just rage inspiring, like BASH BASH BASH or arrows + retreat or any number of other tictacs.
Tell me you at least understand why people are going to call you out when you post two subjects that are completely unrelated, except for the fact that you're dealing with them in game right now, and ask for changes to make your life easier. It lowers your credibility!
