TBH they've pretty much established they don't want job changes going forward from ARR for advancement as the base classes advanced into jobs with Arcanist having a split path to 2 different roles similar to what many other MMORPGs had done. Kind of sad IMO because having every base class having a fork into 2 different roles probably would have alleviated some of the queue times for DPS that have pretty much existed the entirety of the game's lifespan.
