I really don't have a problem killing a few greys to get some higher levels out.

On the other hand I think it silly for a bunch of greys to expect to just xp away untouched til they are 35. I personally don't care if people kill so greys.

Also is should be the jobs other others if they care so much to protect them.

Its a game centered around pvp just have fun with it and know you will get killed. many times if you keep going into a pvp zone.
