Tabard of the Protector?

Just some questions regarding this tabard since I've read different answers. Was this obtainable through any time and day during the prepatch before the gates opened? Or was this a specific single day event?What level did you need to be to start this quest?How difficult was it to complete? Did people camp the mobs? Did you need a group to kill stronger mobs?Have they announced prepatch will be 2 weeks or is that just a rumor? If true, does that mean we have 2 weeks for our draenais and blood elves to get to the required level to do the quest for the tabard? Thanks for your answers!
