I think what he meant by 'new ways of doing things' is how they implemented restrictions for crafting. Instead of the usual 'pick 3 crafting skill and you cant learn any more' they just nudge you into specializing by making you run out of bag space if you try to pick up all resources at once.
I like this approach very much, as i plan to have all crafting skills on my one character (i plan to have no alts this time) eventually, even if not leveling them all at once.
