Pvpers overall live too long not only that but their life is far too safe which leads to them effortlessly killing anything around them. Death simply doesnt apply to them which is IMO very unhealthy for the game.
Here are a few ideas that can significantly lead to more deaths on the pvp side with out really affecting the pve side.
timer to enter any boat when in combat. Boats the most abused way to escape any fight.
Range hearth magic that can be used only in combat to apply a teleport timer. Has no effect on downed players.
redhand = permadeath if kod. Move redhand from battery to theft and up only otherwise its cancer in pvp. Increase the time of redhand and remove any tp timers from it. Its a youre no longer protected by the hearthlands debuff.
Use a scent on any thingwall to get whispers from the thingwalls notifying you which thingwall they reside in currently.
