The Skull Clouds should let players know what kind of fort is up.

Nothing visually sets a guild fort apart from a regular fort. You don't know what you're going to unless you sail there, go into the tower, and peek through the floor boards. I think the skull above the fort should indicate what kind of fort it is. Like if it's a gold hoarder fort, have the eyes flash yellow. A merchant fort, have the eyes flash blue. A souls fort, have the eyes flash purple. Also I do think the amount of loot in guild forts should be upped at least a little. Maybe 25% more stuff just to feel a little better. If not that maybe take away the final Skeleton Lord boss fight just to lessen the overall completion time, since there's less payoff for completing it. I know diving cuts down on the overal time quite a bit though, so maybe that's balance enough.
