And/or in my "AAR" perhaps too: tm.asp?m=4175198
And it looks like it is true (and realistic ofc), because smaller TF at least have no crashes and less losses (not that they hit better ofc), 2 smaller CLs fleets from me survived against larger more powerful fleets, while a big fleet seemed to suffer the penality and BBs sunk.
The other reason suggested by experts is, I was using a night with too good moonlight. But read it yourself if enough time [;)] I lost 4 BBs in bigger TFs for example
As you can see the Allied player can combine and mass his force (also all nations can work together, as they all speak English), they do not perform worse (as can be seen in the combat reports, with Allies using 20-30 ships fleets, yes they also get some crashes but as explained above with better exp of Allied ships this will fade starting in 43 imho)
Edit, also it seems to be true for some reason that mixing BBs and CA/CLs seem not to be good. Like some others already suggested, I have no idea why tho. In reality you need cruisers for recon and screen BBs (not only DDs). But this can ofc only be coincidence.
Edit2, another source is an AAR by "Obvert" ("Elephant vanished"), who experienced the same CV reaction problem and that his SF fleets did perform badly even not engaging CVs (I noted the same things)
