Back at the start of cata i think it was when prot pally was op as hell in pvp with vengeance and self heals, I was at the pvp arena in stranglethorn, going for the chest, the wee goblin walked in mid, I went for it, got attacked by 3 allys, killed them off, another 2 came, killed them, then another 3 came, killed them off, then going for the chest respawners kept coming back, so instead of killing and hoping for chest I had 8 allys all on me at the same time, we fought for ages, I didn't go down once ( op world of glory heals ftw :P )
I killed them off so much that all had a 60 second respawn timer and i got the chest, after it there was 3 or 4 horde on mounts above me and just whispered, *Holy fuck man, we just sat and watched all of that, just epic* needless to say i had the biggest smug smile on my face and felt like a beast :P
