Sure wedges are iconic but they are boring after a point.
You seem to be confusing personal opinion for facts. Myself I'd much prefer it to keep the wedge shape as much as possible so my list looks properly Imperial on the table.
3-4 ships is not an Armada.
So? If you ever thought you could control a true armada of 20+ ships, you got the wrong game. This was never going to be more than a 3-5 ship game.
Understand the tourney scene is popular because people are ridiculously competitive people but there a host of people turned off by the game because of the tournament scene.
Those people have only themselves to blame if they don't get into the game because it happens to have tournament support. They are also going to be a much smaller number of people then the number who get into the game because it offers tournament support.
To be clear, there are going to be more people who don't play in tournaments then do, but very few who avoid the game completely because it offers something optional they don't wish to take part in.
They could have made efforts to encourage both is what I am saying.
And what exactly can they do to encourage casual non-tournament play?
