I am for intra AC dual spec. I do not want AC switching I think that might go too far. Players switch specs all the time. A dual spec feature will allow players who often change roles or specs save money and time(increasing quality of life). Players who don't change thier spec might experiment with a 2nd spec perhaps they will find another spec or role more enjoyable than the one they were before. I have a hard time seeing a downside to allow players to have an easier access the the entire class they chose. I think the feature will increase the activity of players doing group content as more players will be able to fulfill different roles.
