3/18 WOW ninja patch

Hotfixes are server side. For example they can patch dropchances/cc immunity/respawn behavior without doing anything to your client, they don't even have to restart the server for some things. You could see this clearly when they hotfixed firelands trash - I personally observed this when the mobs were changed from one pull to another, when farming the fast respawning mobs. So no this zandalari thing surely does not need a client patch.
