Well many (who had no experience with cast times mind you) were complaining at first about WM but now that players have actually taken time to learn it, it's not as bad for those individuals.
Bard still has more mobility then classes out there and SE will eventually add new jobs, if they are support or not we do not yet really know.
Some had suggested Ranger and such as a possible branch off but i think the current Archer/Bard setup is here to stay.
