Here are a few tips to help you with Low level BB play:
1.) Play the middle of the map. Larger BB's usually play the north and south.
2.) Be patient. Wait for the smaller ships to sail into your range. Also take notice of where you can and can not see, as well as if you are scouted or not. All too often, the enemy leaves the middle of the map unscouted.
3.) Target distracted enemies. If 2 BB5's are going at it, try to get a few salvos in. Unless you have a BlackSun or TNF tag, the BB should ignore you and continuing firing at the larger BB. If he falls back, do not chase him. Play smart.
4.) If your BB can launch scouts, use a scout!
I hope these tips help. Sometimes you will have a breakout game where you end up getting 250K attack in a BB1. Sometimes you will have games where 14K seems nice.
In either case, Stay Frosty Out There! Good luck!
