I hope this isn't a report, I searched but couldn't find anything.
With the new patch you donot get teleported to the battlemaster anymore, so this is a really nice way to earn some money while waiting for the queue.
Just fly to any random cave, mine whatever is inside of it, ask your part to join and after that arena match you will still be in that same cave but hopefully now with the veins respawned, rince and repeat this for some decent money while waiting for the queues.
Really any cave works for this but personally I would go to the north of camp tungalo in stormpeaks.
For fishing this is just about the same, but only then find a lake which has nice buff-food pools and queue/fish ahead
This works with herbing/skinning aswell but to a lesser extent since herbs don't spawn on specifik positions and there are always animals around either
