200.
Certain players using blitz BBs and PCAs and getting 900 SD is ridiculous.
It's one thing to have accurate guns. It's another thing to be unsinkable by 90%+ of blitz ships. It's another thing to do that when you're the only BB or CV in the room. And it's a whole different story when there's a tag by your name that makes blitz players see you as a role model.
But since I don't expect that to stop anytime soon, at least reduce the SD in blitz. 900 SD is more cheap than KM SS5 by far, and if you need 900 SD in your BB to win you probably shouldn't be playing this game.
