It's probably been covered before, but I couldn't find anything like this on the first few pages, so here goes:
My main is a lvl 60 hunter w/ LW/skinning. Initially the idea was that I could make some decent gear for myself along the way. In practice that hasn't turned out as well since my LW skill tends to lag behind my lvl, meaning for example, that my lvl 40 hunter could only make lvl 30-ish gear.
Now, having made it past 40 when I can now wear mail, I find that LW is even more limited. My primary frustration? It seems that just about all the craftable mail items have +Stam/+Int, but no +AGI! I realize that Stam and Int are important, but from everything I've seen, Agi is even more critical for hunters. Maybe I'm wrong on that, but I don't think so. It doesn't seem like BS is any better since most of the high end stuff there is all plate (and the mail items have the same issues - all Stam/Int, no Agi)
Maybe I should just can the LW and pick up mining, but there's part of me that really enjoys the crafting aspect. The only problem there is that most of the stuff I make doesn't seem to have much of a market, so I end up either selling it off to a vendor after losing several AH deposits trying to auction it or getting it DE'd and selling the resulting enchanting mats (also frquently at a lose tking into account the deposits I've already paid).
Oh well, I guess the system isn't perfect. I just wanted to vent a little. Feel free to add your own trade skill rants.
