As you know, I used the Blackwind Sabercats (found in the Skethyl Mountains) as my Black Morass comparison beast. These mobs range from 70-71, about as close as you can get to the dungeon level beasts outside of a dungeon. Since I had already done number crunching with them I thought they would make a good test case for the changes to skinning too. Plus the fact that they are the highest mobs you can find, so hopefully the skinning increase would be more obvious too.
I skinned 25 of these on the PTR vs 24 on my live realm. In case you don't remember the drop rates from my live test, here they are again:
Knothide Leather: 16 out of 24 skins
Knothide Scraps: 8 out of 24 skins
Pretty much a 66% drop rate on leather, 33% rate on scraps. Now here are the numbers for the PTR skins:
Knothide Leather: 19 out of 25 skins
Knothide Scraps: 6 out of 25 skins
Now from this sample it looks like the drop rate for leather is up slightly. The downside is that yes indeed, six of my cats dropped one scrap. This after we were told "Skinning higher level creatures will give more leather; you will no longer get a single leather scrap." I'm really hoping this is just a wrinkle in the plan. On the other hand...
I went to Cosmowrench in Netherstorm and skinned the 67-69 warp chasers and skywing critters and got:
Knothide Leather: 5 out of 15
Knothide Scraps: 23 out of 15 (yes, you read that right)
Wind Scale: 1 out of 15
Nine of the fifteen mobs dropped scraps, each of those mob dropped 2-3 scraps and no mob dropped just one scrap. So the drop rate on knothide was much lower than my Blackwind cats, but I did get the multiples on the scraps as promised. So for this area I was able to confirm the changes on scraps, although I still think the drop rate on full leather is too low. Almost twice as many mobs are dropping scraps compared with full leather. From this I would guess they didn't adjust the drop rate of knothide leather, they just beefed up the volume of scraps you receive when you get scraps.
At this point I'm not sure what I think happened. Somehow my cats got overlooked in the updating process? They appear to be minimally affected based on my results. If we assume that the Cosmowrench sampling is indicative of the actual change that was made, those results aren't terribly exciting either. More scraps, but no meaningful increase in full leather drops. As I said at the start, up to you folks to decide if this is a worthwhile improvement...
