BC items include Feral gear

[Kevin]

Does that mean, that stamina remains the same on the pre BC items, despite the fact, that these items should have much higher stamina values according to the post BC item value formula (stamina gets cheaper and items have therefore ceteris paribus higher stamina values )? If this is the case, that would mean a huge(!) nerf in ilvl to most current items after BC gets released. Not only they will be outdated because they were designed for lvl 60 in the first place, but they will also have much less stamina then they would supposedly have when designed with the new BC formula for item value allocation in mind.

Lots of Nexus Crystals incoming I guess.

It's my understanding that old items won't be changed with the exception of some of the hunter sets because of the big ways in which hunters DPS are being changed (1 agi = 1 RAP instead of 2, 1% crit = 33 agi instead of 52). So what I've read (and since I don't have a source take it for what you will) is that hunter sets will be the only sets revisited because hunters are getting bigger changes than other classes and it would break current itemization pretty badly.

I think they are intentionally not changing other items precisely to make it obsolete that much faster so that people get on an even footing faster. There's a portion of the population they've gotten hooked on the end game raiding now that is anywhere from slightly behind to way behind the gearing curve of some of the older raiding groups. Since even with 10 new levels of content and smaller sized raids, raiding is still going to be the end game of TBC if you can get more people in it together Blizzard wins. People who will be starting the game or picking it back up when the expansion comes out will be able to get back on even ground with the people that may be several major power steps above them. They want everyone back on the same playing field quickly. Making the new items that much better than the old stuff does that.
