I have heard a lot of different dates for the start of Season 3 arena. I'm trying to get ready for it and knowing when it will start is a must. So, when will Season 3 arena begin?

This question has been all the buzz since patch 2.3 came out. Blizzard originally planned to start Season 3 one week after patch 2.3 came out which would put the start of Season 3 on November 20th.

But wait…

Blizzard, yesterday, has actually pushed the start date to the S3 arena and it will not take place until Nov. 27th. The reasoning behind this push back isn't a technical one but it has to do with that upcoming holiday called Thanksgiving. I really consider it a good move for Blizzard to make just in case tons of bugs pop up and they wouldn't be staffed enough to handle them during the Thanksgiving weekend. I am like you, I really want this season 3 to get off on the right foot and sooner rather than later. Oh well, that gives us one more week of honor grinding before the season 1 items come available at the honor vendors.

Here is Blizzard's official post on the matter:

Everyone is preparing for the start of the third arena season and we’re excited to get new items, rewards, and fresh competition going for everyone participating in the arenas.

As we approach the previously announced start date we’ve had growing concerns of what the new season requires of us to actually launch, and its proximity to the Thanksgiving holiday. Everyone wants the launch go as smoothly as possible, and in order to have resources available to tend to any issues as soon as they may spring up, we’ve decided to delay the Season 3 start date to November 28. One week after the previously announced date.

This allows us to have the quickest response time to any issues should they occur. While making everyone wait another week obviously isn’t the optimal outcome, in the end we decided it would be much worse to start Season 3 so close to the holiday and potentially make players wait longer until a problem can be resolved. Ultimately it allows us to provide the best possible service for everyone as we launch the new season.
