Nexon Korea's next update

Theres no Black Mage boss or npc or anything other than name dropping in the game right now?

This is an MMORPG. Adding a final boss is redundant. Take WoW for example. Each expansion releases new content leading up to the final boss (ex. Lich King) until the next one ultimately releases with a new, more powerful enemy. I'm betting we won't even see the Black Mage as an enemy for quite a long time. We still have two more heroes after this patch to release yet another area on the Temple of Time (assuming that only one of the two remaining doors open up in this patch). There might be more Resistance Classes as well, it's hard to say.
