I will be unable to play for two weeks and my token runs out at the very day I'll have to leave. As Order Hall improvement and Artifact Research will each run for 15 / 10 days there would be an incentive to bring some twinks to 110 and at least queue up 10 days of artifact research _IF_ it will not pause while the account is inactive. If they pause I would not bother.
So, do they?
I seem to remember normal work orders in WoD not pausing, but this might be different.
