Ok, now this is kinda repost. You probably know already idea of farming Motes of Air on Windy Clouds in Nagrand. It was posted by NecroNz (big thx for it), but I think that some more detailed map would be useful. So I made this one, according to all spawn points I saw and I made some explanations to all spawn points, so it'll be easier to find it.
So here's the map:
Those are all spawn points where I found clouds. And now some explanations:
01 - close to the village, near one of the big huts.
02 - on the road or very near it.
03 - inside arena.
04 - in the middle of ruins or very close to it.
05 - on a floating island, there are two islands kinda close to each other and i saw clouds on both of them.
06 - floating island - middle of Telaar.
07 - close to the hills.
08 - near lake.
09 - near Shattered Rumblers.
10 - floating island (?), sometimes bugged.
11 - on the grass, easy to find.
12 - floating island with waterfall on it, sometimes bugged.
13 - easy to find too.

16 - near the road, saw it only once.
17 - there are some floating islands and you can find it on all of them. Sometimes i saw 2 clouds on big island.
18 - small, single floating island.
19 - there are 2 floating islands (one with waterfall) near Halaa - you can find it on both of them and one NE of it)
20 - obviously easy to find.
21 - big floating island. You can find it on hills with Shattered Rumblers little bit to the east too.
22 - floating islands above the lake.
23 - on the lake or near it.
24 - north of village, easy to find.
25 - it can be on one of the floating islands or on the ground.
26 - near birds (forgot the names).
27 - -||-
28 - easy to find too.
29 - near ogres mound.
30 - on the road or very close to it.
31 - near the little hills as seen on map.
32 - big floating island.
33 - on one of floating islands or on the ground near river.
34 - near river and Garadar.
35 - near lake.
36 - near bigger lake.
37 - easy to find.
38 - easy to find, little bit north of arena.
** - near the small floating island, everytime I saw it, it was bugged.
Windy Clouds can be farmed by all engineers that have and can use Zapthrottle Mote Extractor. Every cloud gives you 3-5 Motes of Air and they keep respawning, so you can keep farming them. It works the best with epic flyer of course. On my realm I can easily get 10 Primal Airs in 1 hour, though some spawns are often bugged.
I hope it helped someone. Bye and good luck farming.
