Wierd Little PVP Encounter

I was just out with two of my characters last night (this morning server time) to catch up on a couple of quests I missed when I took the team through STV the yesterday. The Capt and Sgta were just down on the beach near Booty bay when a Lvl 70 Orc Shaman called Brucex showed up. I was out in the open and exposed and thought I was going to be dispatched fairly quickly. He made a move toward me on his mount. He seemed to be attacking so I thought I would go down fighting and sent both of my kittens in to attack. I then backed away and started spamming all sorts of shots into him. He moved in on the Sgt and I thought he was going to melee her so I popped an intimidation on him and continued to spam shots. Within about a minute or so he was dead. I couldn't believe it. He should have creamed both of my characters in seconds with that sort of level difference and equipment. Anyway I decided that I didn't want to stick around to let him have another go, so I dashed back into Booty Bay. Then flew to Darkshire and rode down to the Venture Company site to kill Geologists.

About 45 mins later this guy shows up again and attacks. I set the kittens onto him again and try to kite him fully expecting him to kill me quickly. But no, I manage to kill him again by using Bestial Wrath twice and jump shotting him up and down the road through STV. At no time did he hit me hard, and the only spells he cast were Earth Bind totems. Now, this seems all totally weird to me. The only explanations for this that make sense to me are; Firstly, that he was bored and wanted to go and tease some low level players for a while. Secondly, that his kid brother was using the account and didn't really know how to control the character, or lastly that the account had just been sold/power-levelled and the new owner didn't know how to play that character. Those are the only reasons I could think of that I might win against a player of that level. Anyway, I managed to get 2 kills to add to my total of honourable kills and a whole lot of honor points as well. I guess I should just thank my lucky stars and of course Brucex too.
