I´m not really worried about the subclasses TBH, the moment they put the base class I´m sure that the subclasses would come on as mods eventually (there are even in the EA) and the subclasses do not have unique dialogues anyway so...
Once they increase it they have to deal with all the new spells and abilities - but I think it would be good to not delay it too long. The new area feels like you shouldn't be level 4 when doing it, but let's see.
Or maybe it´s that I really want to start throwing fireballs, It does not feel a D&D game without them =D
