It's really very simple, imo.
You cannot make everyone happy and it is a sure road to failure when you try and do this. They work on space, the WiS supports whine. They work on WiS, and the space supporters whine. And then even within the groups of supporters there will be subgroups that whine. Someone will always be unhappy. It's a harsh reality. The only thing you can do is to make sure that you do not make a majority unhappy. Which is what Incarna did.
This expansion, we're getting a ton of really awesome stuff. CCP did a full turn and got things back on track. Yes, it is space, which is a part of EVE, and plenty people care about that. How do you know this? Because subscriber data shows just that. This is not a case of "listening to the forum whiners" because they are, at best, a vocal minority. This is a case of a player base voting with the subscription button. And that is what has effect.
I think it is too soon to say CCP "has abandoned" WiS. That's just needlessly spreading panic. Wait and see. Besides, we are getting
three racial CQ this expansion. So that pretty much voids the argument. Yes, it is great and all to brainstorm on what more could be, but such things take time, and CCP is not entitled to exclusively develop one feature. Loads of people play this game. They all pay so that CCP can make the stuff you want. So if you want something, understand it takes time. And if you don't like that, you're free to donate a huge chunk of money to CCP so they can fulltime put a team on whatever it is that you want <_<
Sorry if this sounded like a rant, but it's really getting to me that when we get a finger, people want a whole hand, and when they get the hand, they are unhappy because they didn't get the whole arm.
