Item 1: Give everyone the option to toggle themselves from appearing on the webmap (I'm pretty sure this is easy to do). And/or we can also remove the health/armour display.
not being on the map will help keep yourself from being hunted down would cut down on this some. Hiding the health and armor wont change much in my opinion someone with all dimon will still take someone full health and armor if they get a good enough surprise attack.
Item 2: We look into a cooldown on PVP (not sure how hard this is to do, might be hard, and it might be annoying some circumstances).
I have already said a lot about this (and think i suggested it? lol can't remember)
Item 3: We place modify the cooldown on /back (insanely easy to do).
This is a little good and more bad. If you die after a fight you can instant /back after re spawn and only wait 5 seconds. If you die again is when the effect will be seen. So this will only make the annoyance of an attacker less because it will take him longer each time to get back to you if you kill him and
might make him just not do it. Where as if you get attacked at your home/where you need to be at you can /back get killed again (if they are assholes) and then have to wait to go back to wut you are doing and the attacker wins because he kept you from doing wut you wanna do. He can also still just wait for you make you have to wait all over again just dragging out the pain. It could motivate ppl to first go buy armor so when they /back they might have a better but not great chance.
Item 4: We do nothing, and keep it as it is.
We could... but ppl are being assholes.
You didn't add in an honor system Idea with rules that need to be followed with punishment for hose who break them. This doesn't being no Pvp , just means no being an asshole for no reason. If to ppl have a feud going on and both wanna fight continuously then let them go at it. but if someone starts to pick on a random person just because they came across them and keeps them from enjoying the game they need to be punished. Like i said earlier "PvP griefing".
