I would hardly recomend you that dont do this, stoping the progress of random party memmbers is a great offense and it could have serious consequences.
1. It's not against ToS, so no consequences. 2. Blame developers, not players. Palace is even more boring and mindnumbling than Diadem. Of course everyone wants to get thier weapons asap and never come back. 3. You are such a nice person. If we ever meet, I'll be sure to mess with your "progress" somehow. Just for the sake of it.
