So far, I get the feeling the responses are mainly one of the following:
* Multiplayer improvements
* Mission improvements
* Mining improvements
Continued tweaks, bugfixing etc are "no-brainers", but as far as major features having an impact on the game in general I would sure hope we get planetary landing as a feature pretty soon.
The easy way to do it at this point would be to require "atmospheric shielding" to land on planets with atmosphere and then NOT making that item available. So we'd get to land on barren planets with no atmosphere. "Well whats the point with that?" - you ask?
The way I see it, it could be used to extend all the stuff from the list mentioned above.
*Imagine having PvP battles over planetary surfaces.. in some large canyon... ort inside a dead volcano... I think it would be pretty cool
*Missions could be extended to "find me that rebel base on this or that planet", stuff like that..
*Mining could be done on the surface of the planet.
