When you pick to do a dungeon or primal fight, atleast 3 options should appear!

Story Mode: You are picking this option because you want to do the run while watching cutscenes, and not have to skip. This way you don't have someone telling you to skip.

Assault Mode: You are going for the kill, pure and simple. Highlight this if you want people to skip cutscenes. For Speed runners essentially.

Mentor Mode: For those awesome people who help others learn the fight. If successful run for those who are first time is rewarded double. MUST have atleast one player who has not cleared the area/fight before. (This can't be selected unless a new player is flagged for it. To prevent abuse of double reward).
