For those curious about the skinning process and how it might differ from Outland, I'm happy to report that it's much easier (atm, could be changed anytime) to skill up. In the beginning I was getting a skill point for each critter I skinned, then it changed to about every other skin. Towards the end it got a little wonky, but I think it was mostly trending about 4 kills per point. There were some points that took 10-15 kills to hit, but I'm hoping that was just random bugginess. Still, to get 450 in just a few hours is pretty decent IMO.
When skinning critters you still get scraps of leather mixed in with full leather pieces. It didn't take me long to get up to about 50% leather vs 50% scraps though, my unofficial estimate. So far I've only been getting 1 scrap per kill, but that's on 70-71 mobs so it may go up. Also, the recipe for turning scraps into leather is gray at 375, sorry no free points there.
For those of you who've been scoping your current recipes for Outland items to grind - the Drums of Panic were still yellow on my list. It's the only 370+ recipe that isn't an epic item and the mats are pretty reasonable. At 375 I made three of them and got a point for each one, even though the recipe went green at 377. Here are your other options at 375:
The Arctic Belt/Shoulders use the same amount of leather as the Gloves/Legs, so I opted to stick with those for grinding points since the recipes were orange. I made one of each item and then both recipes turned yellow. So they're only good for the first five points. At 380, your options look like:
Green: Arctic Gloves/Leggings | Heavy Borean Leather/Armor Kit | Drums of Panic
Yellow: Arctic Belt | Arctic Shoulders
I will be banking my remaining 7 stacks of leather until new recipes are patched in and we can continue our little experiment, but this should give you some idea of what to expect when you first hit Northrend.
