Stuck with crafting (leather working)
Bulk crafting will never be the way, it’s all through discovery (and a bit of refining when you first get to a new tier). Are you sure you’ve discovered what there is to find at that level of skill? You can check the wiki or crafting guides. It’s been years since I was at that stage of LW so I don’t specifically recall what’s what. Generally you want to make the highest tier inscription you can (insignia? whichever), then make each of the two parts of an armor piece, then discover that. Given mats, that’s six discoveries per inscription. Plus you can combine mats for things other than armor (runes, eg), though those seldom seem to grant as much skill xp.
I found that buying mats and then crafting them to what I am going to need (i.e. chest pieces, leg pieces, etc.) will get you through the first 25 levels and then discovering (putting the insignias with the pieces) gets you through the next 25 levels.
This method worked for me as the insignias changed every 50 levels or so and you only needed to discover 4 armor pieces. So every time I “discovered” I would do chest, leg, glove, and boots for each of the 3 insignias available at that level. Although an occasional shoulder or helmet had to be thrown in to get me over the next level hump, it worked out very well.
I found this homepage helped me tons with crafting http://gw2crafts.net/
gw2crafts.net — it offers the least expensive way to level via buying stuff from vendors or the TP (with a few exceptions). You don’t have to follow their specific recommendations. However, I strongly recommend you take a look at how they get you to r200, so you can compare to your own experience — you should see a few tricks that are new to you.
