Without quests, it can be hard for players to know what new talents are available to them with the new skill.
I had no clue what to do with Engineering/Fuel Making/Block Making skills until I looked it up on Glitch Strategy.
Also, Master Chef II didn't give me any quest, which is a bummer. You'd think the arguably highest skill on the cooking tree would give you some dynamic awesome finishing quest.
Quests are fun, even if you just sell the items you make afterwards.
The game needs more quests.
