before fixeing the problems about money/experts fix your crew! T_T 4engys4reps 2 AA2main gunners and 1 scout

First, which games are you playing? Great Battle, Blitzkrieg...?

Second, when you class sailors from any of the Lv12 classes (Support Sailor, Armament Sailor...) to the more advanced class, they get lower EXP gain. Neutral and unclassified sailors get 140% EXP, Bridge Officers and Gunners get 120% and everything else gets 100%.

Third, if you are using Hedgehogs, the cost to buy the ammo is insane.

Fourth, as phillip said, you might want to check out the KM Forum. There are guides to which kind of crew you will want and ship setup guides.

we had a thanksgiving boost event where you got more exp but now we dont.

Yea i know my crew isnt great, im planning to fix that later.
but the problem now is that for some strange reason my exp gain just plummeted with the same set up and with the konigsberg etc, and i dont know why it just dropped.

if your on kaiser server i can give you the moneys

I'm not sure what to add. I thought maybe there was a TK problem but you aren't using torps.
Your gain will lower as you level but not so drastically and there should not be such a drop in cred and
point at least.
I must ask though, has it been continuously bad? Was it just one game etc?
If you get 0 attack, your gain will be very low in those games. And likewise, if you get little or no attack,
then leave the room immediately, your earnings will be based on your team's attack which would be very
low mostly likely at that point, and thus you will receive almost nothing.
Another factor would be winning and losing. You receive less on a loss.
So the most extreme situation would be - die right away, no attack, little team attack, leave game early on
a loss. In this scenario, even if you did have a little attack or even won, you would get quite little.

Also when you attack, hitting higher level ships such as BB or CV will give you more earnings. AA is also
an easier platform for all gains. Even a little will earn quite a bit.
Try that while waiting a little longer to leave the room and win.

My final note would be until Monday, there was an experience boost for Thanksgiving. Your comparison
might be based on that. What you might earning now could be normal
The drastic difference could be a factor of attack/win/loss/time etc + changes back to our normal rate.

Im not sure tbh, I just found that suddenly my gain plumetted hard, i was only getting around 1k to 1.5k credits/exp.
The thing that annoyed me was that if i had 0 attack, i got around 1k, but if i had 2k or something it would only go to 1.5k, is this normal? Im just new, i think ive been playing for less than a month, was there some event going on?
The other day though i hit 15k attack and got 5k.

I only play blitz cause i cant AA and obviously id die in one salvo on GB.

Thanks for the help guys, i wasnt aware of the thanks giving event, may of been that.

As for the crews, i dont have ship space for such a big crew? do i just rotate and try to level my other crew (repairs/engys/aa) since my core crew (gunner / BO) are essential.
