Sorry, but I don't care about how myoko performs better than mogami or vice versa.
I just want to know if there is any experience bug.

Richard, I think bottom line Mog41 is better for the simple reason that Myoko is level
47, Mog is 51. AAW is no fun without high level gunners and especially in IJN you
didn't (hopefully) level to DP gunners before level 62 (or 72 or 82) thus you'll get
more xp in the higher level boat.

Level aside, there are a couple of teensy reasons Mog is better:
(1) 151 gun space vs 141 - so you can take a bit more ammo and I have actually run
out of ammo on a Mog'41 doing AAW
(2) Mog has teensy bit better turning force for dodging those torps that the pissed-
off CV whose fighters you just cleaned from the sky send your way.
(3) Mog can fit much more scout planes. A good AAW is also scouting for their team.
For teamwork. No, its true, it happens in Navyfield.
(4) I don't know which ship is faster but with IJN long-range AA guns, speed is not as
important for IJN AAW. In my Mog, it goes 27 to 28 knots without OH which is fast
enough. Although many AAW people think speed is everything but I don't think so in
IJN.

My record credits (with Prem) is 25k. Thanks to some high-level fighters parked at
golden angle over my team's bb's. When they were gone, more came to replace
them. I actually ran out of shells or it would have been higher.

p.s. I also tried Kita with 3.9 and with 4.7 and the gun angles make it unusable. Also
displacement not high enough for fat higher level sailors.
p.s. I also tried Asama with 4 x dual4.7's on each side and that is just not enough
firepower
p.p.s. I'm willing to try a myoko but I have no idea what experiment could be done
that would give a definitive answer.

Team attack is directly proportional to Bonus credit. So you can't say I forgot to take
that in consideration.

i find it that kita sucks at AAing :x

anyway, all i ever used in IJN for AA was the Mogami CL and tsukikei. witht he DD you dont
get much from it, but with the mogami CL you can receive alot. my best game ever done with
it gave me a total of 15K exp to my sailors, though i dont remember the ammount of
credits, but it paid my sunk boat ^^

btw i prefer using the Mogami CL: more speed, and only one slot less than the remodel

good note, but you forgot to take team attack in consideration...

and about the actual bug, i play mogami CA, with 5x6,1" A triples, no problems. But
when I AA with my 10x3,9" A dual DP guns in kitakami i get half exp, i gues tw boat
is not programed for AAing (it's IJN's kinda AA moltke - spam ship) :D

If higher lvl ca get personal xp, then that means I would have been training stuff in
my Moltke already.

Seriously, doing over 5000 credits for just 12-14 k in a moltke is lame if you
compared 12-14k xp with 3000 credits in game.
If lower tier ca get personal xp, then I would have stay in hipper for a long time ago.
The exp system is messed up...

...I'm not sure anyone has bothered to do the research before. The same oddity in shared
xp (and AA xp) might exist for all nations' CAs.
