TBH, this is possible the most convenenient way to grind primal air, not only isnt there any ganking, but you can also farm veins at the same time as you fly around. The have fixed it but there is still bugged clouds where the clouds are on those floating islands but just out of range of the extractor.

I pity the poor nabs who don't have engineering. Having to grind somewhere like the plateu where they can be ganked.
