My beginner mistakes.

Grimbru:   ^This. I tend to be an aggressive player at the best of times, and I have a penchant for fast tanks with nice guns. This often leads to an 'I got this guys!' kind of attitude that see's me taking a risk in order to try and turn the game or end it quickly. I don't necessarily think there's too much wrong with that attitude (risk leads to profit after all), but the big mistake I have a habit of making is not communicating what i'm doing.   There's been many an occasion even in my small battle pool where I've moved into what would be a great, game changing position, only to become isolated and picked off. At the time i'm probably cursing team mates for not having the balls to leave their camping spot , but in retrospect I realise that you can't expect your allies to be psychic. Communication is vital!
