would lvl 50 gunners be good for that???

Svetlana is the better choice if you only have one pair of gunners. Bogatyr line needs
good gunners at that.

I will go to BB line but i have a big problem now

Should I go to CL.Svetlana or CL.Bogatyr

The BB1 is aweful
The Gangut is meh
The IM is very OP, so you can have fun in GBs with that.
The Stalingrad is very nice, all round, the best BB4.
The Soyuz is not my cup of tea, although I do hear people complaining its OP...
The P24 is ok in big BB rooms, good luck in GBs, you will need it.

Tbh I found the IJN/KM/US BB lines much more enjoyable to play.

If your going to go SN CV, you might aswell go DB heavy. If you want to go FP heavy go
US/KM/IJN. If you want to go TB heavy go UK/US.

If your just getting started i would recommend BB line. SN ships are pretty fun to play
when headed in this direction. CV line would require u a lil more resources and more
patience to get to the higher lvl, but ends up "reimbursing" you in the end.

I really wanted to make a sarcastic comment, but I'll go ahead and refrain.

if you are "safe/defensive" type of player, then SN BB would fit into your style pretty
well.
