the attacked gained by torpedoes is shared so the exp you get is lower. As far as aa dont know how good or bad you are with it so i cant really say much.

As other ways you can buy your self a pcl if you want or just suck it up and continue with what you get.

just put off those torp and go aa only if your lucky you could get 10k - 15k(if you get more planes shoot down)

i havent used it as the exp at low levels is good enough and you lvl fast enough. From my side i tried to stay in blitzt as much as i could because it was fun to play (and not being one shooted in gb).

Btw you mentioned aa and u said your gunners are lvl 41....? Are those your aa gunners? if so you should have known that ijn dp gunners should stay unclassed (as arm. sailors) until late in the game somewher 80-90 depending from you as that way they become way better. if you already classed them then there is nothing to say but you should have checked the forum first.

Anyway as far as the premium ships of IJN am not sure if they are worth it. I have the asama and the b-65 project but none of them is good enough if you ask me. Ok kongo sucks big time but i think you can manage to get through until the bb2. Fuso rocks in my opinion and Nagato is one of the best bb3 in game. BTW with Fuso i had a few 100k+ games which were so lovely :) i love going after Monties and h39 with that thing. 16.1 guns and the 12 shells of terror. Oh and up to bb4 you have to implement ninja tactis.

Good luck with grind and dont give up once you get to bb4 you going to realizes how powerfull you are.

EBVE acc gunners you say?
You made a terrible becision when picking your ship line because you should have picked mogami.
With it you could use the 6.1" triples for AA (their best non DP gun for AA).
Kuma is a ok AA ship but... it needs high level DP gunners.

Right now you have to grin and bear it till you get to Myoko so you can AA with it.

I also suggest skipping Kongo entirely.

No range no power no durability.
At least Ise/Fuso had some serious firepower... but kongo... all it has are good AA slots (ones you will probably never use if you properly class your DP gunners) and good speed at level.

Oh and forget about Asama... it works best with high level DP gunners (ones you don't have) and 4.7" A on T slots.

Well you can AA in Myoko.
I leveled 3 engies and a repairer to lvl 80 by doing AA just for fun.
Exp for doing AA in a CA can be suprisingly high (sometimes over 16k without prem) if you manage to kill enough planes (this requires some practice because at lover levels you will usually have only one shot before the planes camp you or leave your gun range.
I'd also suggest leveling DP gunners (if you haven't already) because 6.1" A are the best AA guns in the game (3 barrels per turret awesome range and huge damage) and classig them at lvl 62+.

And of course you can use the kongo if you want... just don't expect much of it.

you have kuma ? go back to simakaze
yubaril is also a nice AA ship

if you play kuma, use tactics,

a good one is to be a Anti ss torper and HH user or depth charge.

an other is to wait till both team bb are engaged in each other, they wont have time to get you before you get in range, if u use this tactics, dont fit gun, make your ship the fastest possible.

good hunt.
