I think I've seen that before a long time ago. Seems familiar. That kind of rivals the experiences I used to have ganking too. It really brought out all the crybabies, which you'd later see all over the forum, as if they were forced to roll on PvP. Good times, before Blizzard wrecked the game to make them happy.
But I also used a NE Hunter. Quite amusing to have your stealth cat do the killing for you. Stealth cat and Eyes of the Beast was too much fun. I'd send the pet into towns on its own to kill players as Rogues and not even need to care if it died. One sinister thing I'd do is just place the cat on "hold" in a popular area such as Nessy, in stealth, on aggressive mode, while I'm in Shadowmeld somewhere(often AFK), and let it kill everyone that came along entirely on its own. Player comes in, cat ambushes from stealth, kills them, returns to stealth. I didn't have to do a damn thing.
I also dual boxed enemy chat channel, as Angwe, so it was amusing to see "Can someone kill this skull con angry cat killing everyone at Nessy camp?"
