What level are you on? I didn't even bother with the ARR Masterbooks until I was lvl60 & had decent gear. It's not worth busting a gut for.

The difference between lvl50 & lvl51 crafts is astounding. I came into HW with the best ARR gear (not melded though) & couldn't HQ lvl51 stuff!

Just work through past lvl50 & get the free stuff from the quests. Don't buy any gear HQ from the market until over lvl55 as it's not worth it & gets quickly outdated.

What server are you on? A lot of servers have crafting communities who will often help out to get you geared up. =)
