I am currently level 34 and it feels like I've explored a good chunk of the map. I thought 50 was kind of "end game" but from what I've read on forums and chat, 50 seems to be just the beginning? And there are a lot of "i levels" (items?) and quests associated with those? So once I hit 50 is there still lots of story and lots of world exploring to do, or am I getting close to having explored the map aside from HW content?
