The AoS event, for example.
I think I spent more time on the forums and random other websites looking up what items drop and how to get them than actually playing the game. The only reason I even knew there were new items, or that they came from different factions is because of the forums in the first place.
So, what does the average player that might not even know the forums exist even DO? Do they just play normally and miss out on a ton of stuff that may or may not come back?
