Seems like the levels are off on most or all of the crafting. This was the first thing I was able to craft at lvl 0 not at 2. Unless they are saying this becomes trival at 2 and then I just don't understand the rankings here. They seem to sell very fast on the AH so it's a good beginner one.
Rather than give crafts one number next to them, it would be better IMO to put two numbers next to them, the first denoting when you can first begin to craft that item, and the second number denoting when your skills ups stop.
As for Chocobo Fletchings, you can begin crafting them at level 0 and you will continue to improve your Clothecrafting skill up until you are a level 2 Clothecrafter, which is what the 2 Allakhazam has represents.
No, that's how some jp sights have done it but it gives you a general level for the skill. The skill level they give you on Allakhazam is supposed to be when you stop making experience for that skill. So if it says level 2 is the skill level, that doesn't mean you can't make it at level 0, it means you shouldn't make them past level 2 if you are only synthing for skill ups. If you notice that you are gained xp on an item past that cap level you should submit that as a mistake, but for the most part all the lower levels are worked out.
On an exceptional result, you can also produce 8 fletchlings from two feathers. I did it 3 times last night. (You might be able to produce more as well).
