I made my way to winterguard to pwrlvl at the onslaught camp when I noticed that alot of npc's at winterguard were not even visible to me....I couldnt reapir. So i decide to follow a quest guide that has helped, but lving is taking forever and I am going to just go back and grind at the good locations.

Is there any problem I could run into once I hit 80 with the majority of that Xp from grinding? Will it be easy to go back and do quests that i need to do to open up the daily quests? I have completed all of BT quests and about 40 in HF
