What does this even mean?
Does WotC need a shrine to EGG?
Probably vary tremendously on who you ask but...
Elimination of racial pantheons.
Elimination of Greyhawk (until proven wrong.)
Rewriting vast swathes of history (Io/Primordials,etc....)
Each campaign setting smashed into the model for 4e (Eberron handled this better than Forgotten Realms in my opinion)
Deliberation reduction of core monsters/classes/races in deliberate effort to sell future volumes.
Lack of multiple print adventures.
Lack of setting boxed sets.
Lack of printed campaign support.
etc... etc... etc...
(Note, not saying these are my issues with WoTC but that they are easily some of the things that I've seen crop up when discussing the 'history' of the game.)
