World of Raids has been releasing information by the bucket loads, and one intriguing little morsel has caught our eye: The addition of four new bag types, marked "Leatherworking Supplies," "Soulbound Equipment," "Vanity Pets," and a fourth one simply marked "Unused."

Almost any vanity pet fanatic will tell you that one of the hardest things to do is deciding what to delete to make room for your newest little friend, or which pet to take out of the bank and parade about when heading out to quest, grind, or raid. The idea of making vanity pets easier to store and carry has been one that's been a perennial topic of the suggestion boards and an issue dear to the hearts of every pet fanatic who's set up elaborate trade agreements with the other faction or spent countless hours in Zangarmarsh just to make sure they got ALL the vanity pets possible, and it looks as if Blizzard has finally answered their prayers.

The leatherworking supplies bag is a bit harder to pin down. We already have a leatherworking bag category, so this may be simply a shuffling of data.

As far as a soulbound items bag goes, if it simply allows any type of soulbound item or gear, and comes in sizes greater than the current 18 slot standard, this could be great salvation for any class who carries around an extra set of gear for various situations, be they a Druid with tank, DPS, and healing sets, or a raider with various resist sets.

Of course, we can't say for sure yet if these new categories will be used right away for Sunwell loot or recipes, or whether they're simply in reserve for possible future use, but the prospect of more bag space has this druid drooling.

Here's a really interesting undocumented note from the latest patch: Angelhunter on LJ says letters (as in saved copies of mailed ingame letters) are now soulbound. And that's a huge deal, apparently, to roleplayers -- they used those little scraps of paper for everything from treasure hunts and "official" documents to invitations and tickets.

Now, I'm not quite sure exactly why this change would be made -- for what possible reason would you want to keep people from trading saved copies of in-game mail? It's not like it would stop anyone's communication -- anything goldsellers could say in these sheets of paper, they could say in in-game chat just as well. And I can't think of any possible way that these saved letters could be used to do something devious like pass secret letters or communicate across factions-- there's no reason to make them soulbound by default.

Of course, it may just be a bug -- that's what someone was told by a GM, so maybe Blizzard will put a fix in, and RPers can have their murder mysteries again. Unfortunately, I can't seeing it justifying a hotfix -- odds are that even if it is just a bug, RPers will be waiting quite a while until they can trade letters again.

A member of the WoW Ladies livejournal group, Tsuraibara, and her husband figured out a completely awesome way for them to customize their wedding rings. Since they "met on an online game, the engraving was free, [and] 'soulbound' sounds nice even if you aren't familiar with WoW," they actually went out and got "Soulbound" carved on the inside of each of the rings. That's great!

I liked the plush Shammy a lot, but I think this might be my new favorite real life WoW item. Of course, this does mean that they won't be able to put these on the AH anymore. But if for some reason an upgrade drops (maybe on a wedding anniversary), a vendor could probably offer them a few gold at least.
