Its always going to be a matter of whats more important for this game now, so while I agree at this time it isn’t a priority it should still be introduced at early stages when things start to level out. I think there is enough water for small row boats and rafts, but anything bigger would have no place currently with the limited bodies of water we have. Even row boats and rafts would have limited use outside of RP and maybe some faster travel over water to a base but atleast the function of a player interacting and using the water craft, making it, placing it down for use, etc could be explored and worked out.
It doesn’t need to be in the next update or even this year but if there are plans to eventually expand on the amount of water we have, given we already interact with 2 groups of pirates who had to of sailed open waters at some point, then I think it’d be wise to collect data on the existing waters before going full scale. Otherwise we may end up with boats that squeeze through water it shouldn’t and content becomes rather dull when its broken in appearance. This whole concept wouldn’t be complete without water creatures which we still don’t have so it’s something far fetched but I think it’d do a lot for the game as a DLC down the road.
