This is feedback mostly aimed at the development team.
From a recent interview:
For my part... I'm not overly fond of sidequests for the reasons touched on, but I do feel the writers did a bang up job. There were some story/quest lines that were really very good.So you thought about completely removing the experience reward from sidequests?
Y: Even though sidequests are based around story, if you want to progress through the game quickly you can click your way through them without reading anything. Because our questing system is not all that elaborate, the tasks themselves are limited to a small number of variations like "Kill X of that monster" or "bring this thing to that person". Of course we are working on including more varied tasks, and we are also working on main the story itself interesting. Still, we had to ask whether a system that allows you to earn experience just by clicking things was really needed at this point from a game design perspective.
So you had that conversation in the development team?
Y: In the team as well, there were people asking "can't we just remove them already?", but we were worried that if we only allowed players to level through group activities like dungeons and hunting open-world mobs, then we wouldn't be able to provide for those people who want to experience all aspects of the game on their own. There were arguments in favor of both sides, but in the end we felt having experience rewards from the main quest wasn't hurting the game in any way, so we decided to add side quests as originally planned.
How have players reacted to this?
Y: I was expecting a few more comments like "We're sick of them" or "There are too many errands", but I think we were able to make the story interesting enough to cover for the monotony of the activity itself. In the end, expect for one particular set of quests, we didn't receive that many complaints. I think this is thanks to our writing team's efforts.
I think varying the tasks is a good idea but I hope the writers will keep it up too.
