FS#5914 - Skill Requirements and Time Locks
Most quests start with an intro and a confirmation for the player to accept the quest. For those that have skill requirements and/or time locks, instead of hiding the quest completely, perhaps it would be better to expose such quests when the character is otherwise qualified (e.g completed other quests in the chain) and do the skill / time check in the intro steps and have the NPC inform the character that they need to practice more before they can continue, or say something along the lines of "too busy right now, come back tomorrow". This way the player will know the quest is there, and get a hint of what they need to do. Going around and touching all the NPC's and finding nothing just feels like a bug when one knows there should be quests out there someplace.
