Writing a pretty extensive topic on improving for higher level players (2000+wn8 above) but it'll apply to everyone, just that those people will comprehend it better.
If there are any questions you'd like me to include, I will as long as the topic isn't finished by the time it's asked. This is a general improvement guide, so nothing map/tank specific, but larger concepts. (Improving situational awareness for example), if there are any: ask!
