And let's not forget the main issue when speaking about complexity. There's complexity as such and then there's complexity that has been well factored into the actual gameplay - not just stats in inventory but something you can actually see and feel when you play. In other words, meaningless and meaningful complexity. There is no evidence whatsoever that complexity has been diminished in the latter sense. Some examples of removed features is known but there might be as much if not more added features of which we have no knowledge yet. There could be overcompensation for the removed features such as the much - loved pauldrons and crossbows.
im not sure I understand what you mean about meaningless and meaningful complexity, but I do know that removing so many core features cannot possibly mean more complexity.
I mean how could it, it really doesnt make any sense.
