Recently, while leveling an alt on a PVE server, I had to contend with level 90 toons from pvp realms, killing the quest givers in hellfire peninsula, and camping the pvp fortifications to gank levelers minding their own business on their PVE server.
It's one thing to have 90's from my own server taking advantage of the situation, which on a pve server doesn't happen as much as on a pvp server. However, having 90's from a pvp server in a 60's area of a pve server is not cool. That is harassment. There is no need for a pvp server toon to be in a leveling area of a non pvp server.
I have a solution though. Since certain Bliz officials want to encourage such bad behavior, how about some other Bliz officials stepping up and making this interesting? If a player from a pvp server goes to a non pvp server, all their stats get a debuff, equal to the zone they are in. All 90's from another server that go to hellfire get a debuff that makes all stats: health, mana, damage attacks, and pvp stats made equal to those leveling in Hellfire. That way, if they do not behave as guest on another server and overstay their welcome, I can get on my 90, from my server, and give them a taste of their own medicine.
We had the ganking thing shoved done our throats. We have transfered to a nonpvp server to get away from it.
Either get the pvp'ers back to their own realm, or give me my money back because transferring to a non pvp server didn't do a dang bit of good.
The cross realm thing sucks and Bliz needs to police up its mess.
