I would like to make two suggestions. Convoy
: I would like the ability to create a trade convoy. This would require some new UI creation. In essence this would work similarly to how a trade route currently works, but you could assign multiple ships to the convoy. The whole convoy would stop at every island selected, but each ship could have it's own specific goods to pick up at each location. Military ships could also be assigned to the convoy (either picking up goods or not) and these could escort the convoy for protection. All of the ships would wait for each ship to load and unload goods before moving on to the next island; traveling together into and out of each session location. This idea would allow for better protection of trade routs, currently you need at least one military ship for each trade ship; with this idea you could have (as an example) 5 trade ships protected as a whole by three military ships. In a world where there are pirates, this only makes sense. Diving:
I'm one of those people who dislike the crown falls area, purely because it devalues (in my opinion) the old world as a whole. I don't like the fact that crown falls is so large that if you use this session it only make sense to focus there due to the abundance of space. However, I do like the diving and Old Nate mechanic there. What I would like, is an option to disable the crown falls area and move Old Nate to the Old World as an additional NPC trader. Thereby I can still enjoy the whole diving mechanic without having to have the crown falls area enabled.
The convoy mechanic especially is one I'm very surprised isn't already available, and if I had to pick just one of these to implement that would be the one.
Anyway, those are my suggestions.
Thank you for your time and attention.
