I buy B65 as my firts premium item and I have opossites feelings about her as long as I try to use her.
Late I have much fun with B65 but at a Nagato level crew... but at lower levels I havent find a way to use it without anger-quiting.
so it s the config
R slot Front: 2 x Trip 12.2 guns
R slot Rear: 1 x HH
T front: 6 x D 4.7"/45 Type 10 A at 27°
T rear: 6 x D 3.9"/65 Type 98 A at 38°
My OHSpeed with 5 engies arround lvl 88 was 48, if u add rear trip some like 45° (I need speed because im a sub fan and I drive BB very bad... :( )
But AAW work give me a lot of E/E (experts and experience) while I was slowly adquiring Big Guns ability, b/c AAing enemies planes make blind space arround B65 if prop handled.
NOTE: the mixed AA give me a very extense cover area (long range cover with 4.7 as all know, and near cover -where 75° max ang of 4.7 fail) and make feel enemie that several AA ships in ur zone so CV drivers think twice before sending planes to your position.
Yesterday I reach Yamato.... and style of play is in some way similar to my B65 experimental config... only that I have much more range now & I can blind some BB and hit them much easy while I continue learning to move and aim...
