I like the new crew features, but still find them lacking.
What I would _really_ like to see is, when creating a crew, a way to type in a description of the crew's goal as a way to help potential crewmates decide whether to join (which helps the creator as well). For instance, you could set it to "high level plunder", "L7+ EITC ships", "going to Kingshead for grenade quest", or "whatever we find". I hate when I join a crew and spend the time just sailing to an island to go hunting, w/o attacking any ships along the way. On the flipside, if you wanted to do something on an island, a description tag could really help you find assistance.
My crew nightmare: Sometimes as captain I like to raise the sails and take one of the rear cannons on my frigate. I HATE it when someone else takes the wheel and starts sailing, and then refuses to let it go after I ask/demand repeatedly. This has happened more than once. I'll always offer to let them have it next launch, and they just ignore me. This has sometimes resulted in me targeting all of the highest level ships in an effort to get us sunk.
