No I wouldn't complain at all. I am not a fan of PvP in the first place. And again you roll on a PvP server you know you stand the chance of getting ganked and corpse camped. It is no different if it people on you own realm. If they removed raiding I would stop paying since that is what I like to do. All in all this is a game that I pay to waste my time. If it no longer is fun I will move on. I feel no loyalty to continue paying for something I no longer enjoy even if I have paid for 8 straight years of it.
I didn't word my previous comment correctly though. I meant complaining about any type of PvP happening on a PvP server is silly. If you feel you are being griefed then you need to report those players for harassment.
