You're lucky you're in a seva,choosing to go down the Alaska and Nevada way which
are the worstly ranged BB1's, harder than the seva. but thats how you larn to play
USN. you need to judge the situation, scout all the time for your team, pick off
occasional ships that get in range and learn to rush a bit, fire a salvo, and turn back
out of range, with PLENTY of dodging

Thanks :) Whens a good time to rush in?

stay back...become AA bb...and snipe down scouts. Also, you must learn when it's
safe to charge in, shoot once or twice and run away. That's how to use the Sevasti.
