Not all of the admin staff are qualified to develop the game so I don't think doing this would make much of a difference, the purpose of this game is really to collect items anyways if you look it hats are used as rewards for pretty much everything apart from the season leaderboard.
Also if you look at the progress graal has made although it feels slow there's actually quite a lot that's been done. You can't expect then and it probably wouldn't be a good idea to release new content too often as it would wash out what the game already currently has.
Also graal only really has mini pointless quests, I think that a big story line with multiple little quests that lead up to something bigger would be much better but I don't think at this point it would suit classic, who knows?
