Corrupted Blood incident , will this be something?

If you remeber and played in vanillla, when you raided ZG there was a debuff that killed nearby allies.
People took this to Ironforge and it spread fast and it took blizzard a week to patch it so it was chaos in a week or something.
Will you patch this before release or after it takes place? Because it is really a nostalgic event for some of us and i hope you let the "aids" spread and then patch it.
