This afternoon I worked on the new Leatherworking recipes for WotLK and I have to say.... they're kind of a mess. First: the pricing is all over the place. The trainer recipes start at 350 skill and the first four recipes cost 11.4 gold each. The next five recipes (still 350 skill) cost 5.7 gold each. At 360 they go back up to 13.3 gold, followed by 15.2 gold for the 370 recipes and the 375 recipes. Does this look funky to anyone else, or just OCD Kaliope?
Another problem I see with the recipes is that they seem unevenly distributed. At 350 skill you get a whopping 9 new recipes, followed by 2 more at 360, another 2 recipes at 370 and the final 2 recipes at 375. Surely they could have spread this out a bit more. An even bigger issue is that 5 of the the first 9 recipes are for casters (the 'verdant' armor) but only 2 are for melee (The 'arctic' gear). If you're a caster this is great, you get all your new goodies at 350 skill. If you're a melee, this kinda sucks because you have to skill up 20 points to access all of your new armor. I don't know what the rationale is, but it seems reasonable that you could give each class 2 new items per skill level. This would make it more fair and probably smooth out the leveling process by have more recipes at each new step instead of frontloading them.
The final problem I see: no Hunter or Shammy gear. I can only hope that it hasn't been implemented yet, but so far we've seen nothing for mail wearers in Leatherworking or Blacksmithing. I would almost argue that they could drop some of the the Verdant and Arctic pieces in favor of a few mail items. Six pieces for a green quality armor set is probably overkill. You could easily convert both of those to 4-piece sets and add a new 4-piece set of mail gear. Even better, do two sets of mail armor and give each class one new item every 5-10 skill points.
And then there's the one sad rogue piece that's actually marked as cloth. Now, I realize that some of the things I've mentioned are basically cosmetic and that's what Beta is about. But this list completely neglects two of the four classes who currently use Leatherworking, which seems like something that should have been ironed out in Alpha if it's a mistake. If it's not, I think there's going to be a lot of very unhappy Hunters and Shammies who have to drop LW because it no longer offers them primo gear.
