yes that pretty much a DUH... playing on a pvp server means PVP WILL HAPPEN.
so much tho if you do a search you find blizzard even saying they have no problem with ganking or camping on pvp servers cuz thats what you sign up for when u pick ur server...
no one is forcing you to play pvp hense why u can roll pve and have all the happy times u want with no one killing u.
