These kind of posts put a lot of pressure on the team as they are already aware of all the issues you mentioned above. Leo said that it's not their first online game they launched so rest assured that they have a specific roadmap to launch and every step must be considered carefully. All you can do now + other testers is wait for a patch and announcement of introducing new features/game modes etc.
They were probably well aware that there were lots of bugs scattered everywhere so one clear option was to split the game into tiny chunks instead of getting flooded with bugs and angry rants complaining about the amount of bugs(the rants came anyway..).
Some of the changes that Leo dodged are probably considered crucial in game economics or they don't have the financial capital yet to do them. Remember that how much the dev team would like to upgrade certain aspects, there's always someone above who has to approve the time and money spent doing that.
Last point I will make is that them sharing roadmaps would be kind of cool, but at a company level that takes a lot of resources and probably also has internal implications.(Some things could be sensible and not worth sharing with users).
Don't get me wrong, I was part of original Microvolts CB so I am looking forward for this, but we got to remember it takes resources to launch and maintain a game and resources aren't free 🙂
