What does this change signify? Yet again, Blizz is trying to open up progression. Whether this is in advance of Wrath, when this all will be relatively meaningless, or simply in response to continuing pressure for advancement from players, this is probably a change that will be lauded by those who don't already have what it gives. If you've got this arena gear already, it might seem unfair that people can get it through alternate paths, and maybe it is. But I like that Blizz keeps trying to make it easier to be versatile in the game, to not just have to devote yourself to either PvE or PvP. Players being able to take advantage of all the game has to offer is key to its continued success.
