How dare you come here with your carebear crap. If you don't want to die, run. If you are being repeatedly aggressed, put down your wings so you can't be touched due to the immunity. There is aboslutely no reason for any whining in this game due to player killing. If you don't like it, get out, or get good.
Seriously? Care bear crap? The PvP system in this game is the most carebear mechanic of them all in a sense that people posing the agressor are the carebears...
I know that someone like you probably does not grasp the concept of what I am saying so let me explain:
Attacking someone in this game comes with zero consequences so actually those who partake in such behaviour are scared. If they were not they would go to games with actual open PvP. Actual open PvP means that there are possible punishments for your actions so you think twice before carrying them out.
If Wakfu wants to keep open PvP then they need to introduce mechanics like the agressor dropping full loot when they lose or losing 10 levels or permadeath. That would probably inspire PK hunters that jump into open battles and the like making for actual fun gameplay.
PvP where you got nothing to lose is only good for showing who is actually a scared kid, too afraid to put on the big boy pants.
As it stands the game would be better off to remove PvP alltogether unless agreed upon between both parties. A system that punishes those who do not want to participate, but has no consequences for those wo do is silly. There needs to be something at risk to make this stuff enjoyable. There also needs to be some protection for the weak, since I doubt Wakfu wants to go down a hardcore road. Killing someone 50 levels below you is not a fun mechanic for anyone in a system where character strength is based on level. Another solution would be to make anyone going into a PvP match lvl200 and naked unless you aquired special PvP gear which can be obtained with the same difficulty for anyone regardless of level.
