I've always been a fence sitter on the Frances. It is a good plane, no doubt about it. SR really only is a factor when first converting a group or if you ever have to rail a group. My issue is by the time I can get them, do I really need a 2E IJN bomber or am I already moving to kami's? By mid '43 or maybe a bit later, all of my Nettie groups are effective converted to patrol usages. LBA 2E's are so skittish in attack, they are best used as mop-up after a battle ... great role in that they can kill what might only have been wounded. But then, range is a bigger deal and so still not sure about Frances.
Now, there was a game where I did use them and I did like them. I got the upper hand and needed a good, strong 2E bomber to support attacks. Yeah, '43 and I was still on the offensive. Frances was a good performer then. So, as an offensive a/c I rate it quite good. But, most games by '43 I'm on defense.
Anyway, just my thoughts.
