I'll ignore the actual questions and instead try to provide information that will help you make the best use of the forums:
- Make a post in the general forum and include the following information: the squad that you like to play, the local meta list that usally defeats you, how you place asteroids, how you deploy your forces and how the first 2-3 rounds usually unfold.
- You will then get lots of feedback, not all of which will be useful or what you want to hear, but you'll get pointers about lack of synergy in your build, new build ideas, how to deploy or what your enemy's weaknesses are.
- The more precise and factual you will be, the better and more useful the feedback you will get.
The rules forum is usually visited by two types of people:
- Those looking for a rule clarification or confirmation.
- Those who are really, really familiar with the game want to help with the above.
The thing is that there is a ton of factors that distinguish a good player from a great one, but it takes time, energy and lots of foretought to actually get a hang of it. The rules forum can help with a fraction of that, but the general's forum would be a better place to start in my opinion.
Have fun out there!
