Docks are A+ 10/10 in functionality, but the costs vs how easy they are to be destroyed does not balance out.
In the new world boating and docks are going to be much more important, and docks will also be seen much more often. The issue is that they can be bashed by hand.
The dock itself is almost the same cost as a knarr and yet the dock can be hand bashed but the knarr can not.
Please make docks destroyable with siege equipment, but not by hand.
I'm not sure if it's a thing or not, but setting a minimum spacing of 4-5 tiles between docks could help to prevent unintended walling on lakes and rivers.
Thanks!
