Yes very true, all of this is needed! Especially waves, dense fog, and, for ships getting destroyed, the ship should actually break into pieces and left into a floating rubble...
The area of the Caribbean should be made larger. The Islands should be so far such that Devil's Anvil is only seen on the horizon from PR. I would love to also have the islands ( wild, Kings, Cuba ) and forests redesigned and see some actual weather and storms ( along with Role Playing wind ) in the game. I also have made a thread here highlighting what i wish would come in the game and anyway thank you Mac for commenting on it
