Chantrewe should eliminate tagging all together and have open hunting season where are long as you are outside any city limits, you take that risk of being attacked. What is the worst thing that can happen?
Ryzom would die, or become WoW.
It would certainly be dead to me, at the least.
If I wanted PVP at all times and no way to unflag, there are hundreds of games that do it better and actually make it enjoyable, unlike Ryzom.
