On the Ala Mhigan subject, the Main Scenario now serves that purpose instead. The point of the class quests is to go into their own stories and backgrounds, ones that will transcend changes in the outside world. Say that, for example, Ala Mhigo is taken back later in the main scenario - you need to make sure that these quests will still make sense irrespective of when you complete them relative to the main scenario.
This is probably also why Colbernoux and F'lhamin were removed from the Weaver and Goldsmith quests - their affairs are now being engaged through the main scenario.
To be honest, I wouldn't be surprised if we see Aldis again in a future job quest.
