On a personal level, the choice won't effect me - I still think simplification for the sake of simplicity is a poor choice.
I remember (about 10 years ago, before WoW, ect) reading a bunch of interesting articles about psychology in games and how it plays in MMOs. (The term was still shiny and new.) The relevant piece was discussing how many people 'say' they want simplicity in games, but only 'stay' with those that are complex. The main focus was DnD (pen & paper RPG) vs. competitors. It highlighted how much more complex DnD was, and how people assumed it would be a turn off to new players, but how in reality, those people that were even moderately interested took the time to learn while enjoying the challenge and got an emotionally rewarding feeling of mastery.
I really wish I knew where these articles are, (I found them through a person who's now dead) but even without the citation, hopefully, you'll understand the principle.
