the one thing that bothers me about this is how blizzard did act only after someone killed LK.
bombs were part of the rogue setup at the time.
they were supposedly having a "close" watch on every lk attemps.
you won't make anyone believe ensidia were the only ones to encounter the bug.
you won't make anyone believe blizzard did not know what happened (especially when they hotfix it so soon after).
if blizzard had been properly testing the fight, they would have noticed the bug and it would never have made it live.
I don't say blizzard did this to purposefully catch someone red handed, but...
one happening is fortuitous.
two is a coincidence.
three times, you push the red button, stop the servers, do your job and fix the mess.
it happened more than three times.
ensidia guys were guilty as charged, but blizzard was at least as much. if not more.
