I want to start with a quick bit to @
StrawberryZebra before I delve into this:
The benefits of the MSQ are largely what Faroth detailed: Deeper engagement to the characters and the world. Remember that by not liking Tataru means you've invested your feelings into NOT liking her. You made that decision based on interactions, cutscenes, voice acting, etc. That's actually a good thing. Ask me why I do or don't like Sylvanas or Genn Greymane.
It is just as possible that maybe you don't care about cinematic storytelling and prefer a more Dark Souls/Bloodborne styled storytelling where the world and gameplay is your story and its your job to uncover it. If it's any consolation in my dream MMO the story was actually heavily a mix of both. MSQ leads you to places/regions, but your own thirst for adventure unveils the real stories of locales.
Now, I'll give you the opportunity, if you could change the MSQ to be optional how would the game be structured? Walk me through your ideal interpretation of FF14 leveling to current endgame. What type of flow would varying players follow? A few examples would be ideal. How would I approach it based on my personality? How would Faroth? How would you?
Now @
Faroth.
I have to say I don't buy the whole instant gratification (called IG going forward) ideology being a primary reason for resistance to change. Most of the systems I have talked about are the complete opposite of IG. Adding Materia that changes skill effects/etc.? People were against that because it added fake complexity that they felt would be mathed out. The current system is very IG and my proposed ideas would have removed some of that. I suggested larger raids or savage 8m version of 24ms. This would require more people playing more often and putting more effort in, the complete opposite of IG. Again this idea was typically rallied against because they don't want a raid or die mentality, which people had felt that more/bigger raids would foster.
I could go on, but I don't think IG is a compelling factor in the community's overall aversion to change.
