i liked build 13 looting system, in boarding corpse didn't block the way, in land they did that. btw i guess its impossible to move EVERY item in looting (probably because of ammo mod?).
difficulty and skills: what the? man why should i increase difficulty when i get more skill point in lower difficulty? i was going to say increase the sailing experience gain but when i decreased my difficultly from swashbuckler to lowest possible, i got a lot of sailing skills, it should be like this, in lowest difficulty you get lowest skill point since everything is easier, the strom don't damage your ship that much, the enemy don't kill you in 1 hit, in highest difficulty you get more skills and more items, no pain no gain right matey?
again auto skill, all experiences are very very very low, in comparison with buying and selling :|, just buy a load of 1 million worth gold and you get a lvl or two, fight 250,000 people and you get almost nothing. in first case you can sell them in wilsholm and get more wealth too.
fast travel/go to:man when you have the island map why you should not be able to auto sail to shores? what's their use? as much as i know maps are supper accurate so you can tell one of your officer and say follow this, in town you can tip a boy to show you any place its not realistic at all, specially when there is not a option to disable this effect :S. ;what i suggest: tavern should be added in every town without even finding them/ finding maps of islands should be harder but when you find a map of island you don't need to sail to every port, its very annoying. remember real sailor know where they could, land they shouldn't close to shore to see if their anchor picture come or not, we simple people who try to use realistic sailing should be very close to land to see if the anchor picture shows up or not, since wind is not nice most of the time you are always sitting on your ace.( if i could tell there is a port/shore without moving too close to the land i didn't need this, but we all know how hard it is to find winhelm if its your first time:S)
