Let the hybrid realm idea die, Moradin.
The official answer regarding a PvE realm in any form was already given, straight from the murloc.
Chill out, research other classes, ask questions on the forum, and use the knowledge to.. better avoid or kill the people who WILL harrass you.
generally most people just want to level, and wont attack. people remember who attacked them without provocation.
a few emotes and its generally all good, go on your merry way. can't speak for some zones like STV, but you can also avoid peak hours and quest with a random player or two, maybe more.
It's really not all that bad, guys. When the worst hits, go afk, or log off and go take a break, you'll be wasting their time while they camp for a litle bit, then move on.
If you're REALLY pathetic, just stand there and let them kill you from the start. the enemy feels guilty as fuck, and doesnt camp after a couple obligatory honor kills.
if you make a bad enough name for yourself, people WILL spread word. so if you keep to pacifism you should hit 60 with not too much trouble.
