I do not understand Guild Wars 2. I don’t mean that solely in the sense of the game’s mechanics not making sense (there are definitely some problems with making the stats more arcane than they need to be, though); I mean it in the very simple sense that I do not have firsthand knowledge of the game as someone who actively plays it. My perspective is from the outside looking in, and as a result there are some things that even in my field and with the benefit of a genre knowledge, there are elements I simply do not understand.
This is true for every game, though. If you haven’t played World of Warcraft in five years, even if you used to know the game very well, there are things you almost certainly do not understand about the game that I do. Lapsed players from SMITE probably do not understand the game’s meta right now no matter how good they used to be. So what do you find that onlookers do not understand about your MMO of choice? What misconception or misunderstanding do you see on the regular that you know is wrong partly because of your play experience?
