well there are solutions to the pk thing,
1. remove the "remove pk"/"remove karma" scrolls entirely, make people work to burn their karma,
2. make the above scrolls ridiculously expensive, in a sense that it's preferable to spend time clearing the karma/pk than spending large amounts of adenas often. that would discourage some ppl pking often for no reason. getting some pks every now and then is not really a problem pking every third person you see and then burning that karma for no resources/effort is the problem
3. revert to the older non forgiving pk system where items dropped,
4. give a red person some significant disadvantage that takes some actual work to remove or have some long lasting effects on the character
Then we can finally see who is brave to go red and not have some jackass with over a trillion adenas worth of gear, having a tantrum or being bored, sweep areas with ppl (afk or live) with less than a billion worth of gear.
