The short answer is yes. The long answer is... Squishy shoes, broken glasses, cpq pendant (this will resurface... but it was there in old source too), cwkpq rewards, the new thief star (I forgot the name, but it was supposed to be craftable in old source), medals, belts... Perhaps some new maple island stuff too... idk cause I haven't been there to try the new content. There should be more... but we'll have to explore to see. Certain items I listed above are still work in progress due to new source not fully functioning.
Except for mages and hp washers. Since I heard there'll be a nerf for MoN, it might not be worthy to switch for certain classes (i.e. Buccaneer).
