Hey, pick up crafting while you are waiting in queue! You can switch classes as much as you want while waiting in queue. As long as you queued with the class you want to run it with, you can play anything else while waiting. So if you queued as a therm switched to a weaver. You can level your weaving while your therm is in queue. Once it pops you simply switch back to a therm and be on your merry way of killing.
