I think you got it wrong. They mentioned the Season 4 items needing an arena rating (Guardian's gear). Also, Blizzard said they would announce Season 4 two weeks before it starts.
Great suggestions. I need to get some of those for my undergeared mage so I'm not perpetually behind the curve. Thanks for the tip! (Also, posted about it here)
This is what MMO Champion said. Maybe they're wrong.
"In addition, some of the Season 4 quality items that will be purchasable with honor will also carry a personal and team arena rating requirement:
I think you are misreading them a little bit. They are saying "Season 4". Vindicator's is not Season 4. Guardian's is Season 4. So, Vindicator's will stay without an arena requirement. Doesn't hurt to go ahead and get the Boots/Ring/Bracers now (unless they drop the amount of honor they cost).
Hmm... I was under the impression that they were getting rid of the Vindicator's stuff and replacing it with the Guardian's stuff. If that's not the case, then there's naturally no reason to hurry at the moment. Either way, I've updated the original post to point this out.
Blizzard needs to be clearer on this kind of thing. :)
I was also under the impression that it was going away. It's definitely not. See this series of blue posts.
Ooo, thanks for the info! I've updated the post again so I don't spread false information.
One last comment. The Veteran's gear will be gone once Season 4 starts. If you are interested in have 2 pvp rings without arena rating requirements, you need to buy your Veteran's Band before Season 4 starts. You need to do this because the Vindicator's Band is unique.
