I think it's a safe assumption that just one update 4 weeks after the previous one that Square aren't going to add 5000 quests and 5000 DIFFERENT styles of quest..
It's gonna take time and I think it's definitely a step in the right direction.. I think the future of the side quest system is very bright indeed, the only way is up and Eorzea is still TINY with TONNES of space to populate and explore and add content to once the fundamentals are under control.
Not to mention the fact that the quests add a little bit of depth and background to the world itself which I welcome with UTMOST interest, I LOVE hearing more about the Lore of Hydaelyn because dare I say, there isn't that much of it.
