Simple as that. Plenty of places i notice lately, when there is a WoW reference or picture, nobody seems to know it.
Not even the simple WoW cinematics some still wonder what game it is.
The new generation right now has no clue what WoW is.
Blizzard can easily get new subs from the newer generation by just advertising ALOT on TV etc. Yet they do not.
I feel like Blizzard is abandoning the game itself bit by bit, just realising this after seeing newer generation not knowing WoW.
