Unfortunately, that will likely happen. But at least the infiltrators will shut up now after I've banned them, and if other people try to play hero while inside the Netherworld prison, I can torture them twice daily for the full 7 days, steal their gold so they can't pay ransom - all things I haven't done so far. And if they overdo it, I could use the deportation option. Basically, whatever options there are, I will now use them when I feel like it.
Why weren't you doing this since day one?
If someone did the same thing in a human prison, he wouldn't expect such kind treatment. Why should a daimon prison be any nicer than a human prison?
When I read the announcement, I (and apparently others) thought it meant that netherworld dungeons would start to become a truly scary place. Instead, it just means that the netherworld dungeons will stop being carebear land and will be on the same level of scariness as human dungeons.
I cannot understand your patience with some characters. "You reap what you sow" is the philosophy that's always governed these things in BM, it wouldn't have been unfair or unfun to be just as harsh as human dungeons.
