PVP didnt happen, stupidity happened. PVP is not 20 lvl 50 toons camping a revive point for 2 level 30 toons. Most games have a level restriction to prevent this sort of thing from happening while others may not prevent it but place a negative reward system for such stupidity.
I am not surprised that some people feel this would be ok. Just because it can happen doesnt mean it should. I am sure from some sort of psychological level it could be explained why people would feel the need to do that sort of thing...maybe their mommy didnt hug them enough or they were picked on in real life or they feel Inferior or 1000 other things.
I am not opposed to a lvl 50 or even a group of lvl 50's killing me while I quest, but to sit at a respawn with 20 lvl 50's and grief 2 lvl 30's over 2 hours isint PVP its just wrong. Even though my 8 year old daughter had fun. That should be a clue to the maturity and mind set level required....8 years old, yea thats the ticket.
