Move as a group. Take care of cruisers, they take care of you. Even in random games. Don't stray alone. Because : a) You won't be able to detect high tier destroyers. b) Alone, your AA is not sufficient to take down 2 squads of torp. bombers or harass them. (at least for upgraded myogi) As a battleship, you're a big, slow moving artillery platform. You may have to move alone as the battle unfolds, according to situation, but that shouldn't be the norm. Also don't forget to assign your AA to bombers by ctrl + clicking on them. (Ignore this if you already do)

I'm also getting lag spikes; usually got 30-50 ms; then for a moment 70 + and lag sign appears. I give it to the game being in beta and servers might have more players than anticipated?

Ow, absolutely correcto. -those invisible torps-

My tier 4 BS got 3 salvos from same invisible destroyer until literally saved by a cruiser. It's so close (7-10km) yet you can't spot it. It's a tier 5 IJN. Edit: It was a tier 6 IJN dd.
