This does require a lvl 82 in leathercraft remember... So only people who master in it can even hope to craft the NQ, let alone the HQ. And unless you're at 93 you only have a 1-2% chance to create it. Ontop of that, one of the ingredients is a NM camp drop that sells for 40-80k depending on the server/current market. If you set out to craft say, 10 of these, you are spending about 40k (in my server anyway) per traveler's mantle, so about 410k just for the materiels. Ontop of that you're also paying for the fact that few people have the ability to make this, and beyond that it is still a high-demand HQ. As pointed out, this will last you until lvl 50-ish. I can see 900k-1 mil as an agreeable price... But I'm settling for the regular NQ (which I just bought for 50k).
That one AGI point isn't a game breaker after-all.
And I personally HATE games where good items are easy to get and everyone can run around with the same exact gear. I don't want people to be wearing Nomad Matnles +1 as if it was nothing. Having the best gear is supposed to be hard and done by few. I have a lot of good gear myself, and am envied. At the same time, I envy the extremely rare person wearing the +1 of my mantle. But thats what makes the game fun.
