I'll give the best answer I can, but I'm not staff.
1. What skills does Mazer have? Like if you 0 wrestling and he was being hit, then that could be the cause of archery owning.
2. I can't help with this question.
3. That one sounds like a bug.
4. I've noticed this also, must be a bug.
5. Chars should definently be able to delete after 7 days, so thats a bug.
6. You never could gain from passive meditation on old Metropolis, so I don't think thats a bug.
7. Metro from 2003-Early 2006 was set up this way, and debuffs were effectively a disrupt in pvp.
8. I believe they set it up this way, but I'm not staff so not 100%.
