Again, this doesn't seem very earth-shattering to me. Until they start doing some real bullshit (item/character deletion, gold theft, wipe out my rep with factions, etc), randomly killing players that get killed all the time in PvE/PvP is blah. I do think that it's impressive with what they did, and I'm sure Bliz is taking the proper actions to both fix the exploits and track down who did them. But I'm not seeing the newsworthy-ness of this, which is the course that everyone should be taking with these kinds of things. Hackers like this do it for the attention and prestige, and that's exactly what they're getting right now.
