Recently when trying to get back into Guild Wars 2.
I last remember recently hitting level 80, then stopping. When i returned about 2 years later, i couldn't recognize most of the things in my massive inventory, what class i was, how to play my class, or exactly what I was doing. I tabbed out for 5 minutes and when i came back I was dead and the NPC camp i was in was gone.
After another look, its a little easier to get a grasp of, I had one bag dedicated to parts for crafting a high level Orichalcum jewel, the rest was filled with raw crafting materials and a ton of bags and chests that accumulated over time.
Though if I wanted to go back, i'd have to learn the new specialization feature, and there's an expansion now... uuugh. No thanks.
