I'm all for different perspectives, but you shouldn't start telling the devs how the game should be if you barely know it as it is now. People who support boarding, for example, don't understand that A. the game is perfectly good without it B. it would be a nightmare to balance and C. it wouldn't be fun, and it would distract from the main purpose of the game. These are all things that people come to understand with time. Once again, I like seeing different perspectives, but it's always better to get to know the game first.
EDIT: By "you" I mean new players in general. I didn't mean you.
Yes, but for someone to get to the point that they're experienced they need to enjoy the game enough to keep playing. If some missing feature is getting in the way of that, that needs to be said. First impressions are pretty damn important too.
I'm not saying suggestions like boarding and increased crew sizes shouldn't be shot down, but there shouldn't be an expectation that only experienced players should be making suggestions either. It makes a community insular and has brought down more than a few games I've played before.
EDIT: As an example, I made suggestions about UI improvements; typically the people who are going to make good UI suggestions are those that aren't already used to the current UI. I know you were talking about content suggestions specifically, but this can apply to stuff like weapon balance at different playing levels. Just because a weapon can be countered by very experienced players doesn't mean that a weapon's current stats aren't an issue, in a community this small you don't want people to be turned off before they get to the point where they've got enough experience to play at that level.
