There is no need for more than a $9 bid to allies in AA50-41 +NOs, one unit pr. TT.
So, with one unit/TT, I'd say not. In case of full bid, I'd say I prefer playing Revised if we are going to revert to 100% of KGF games
I'd be pretty happy to get Allies in this setting. The bid rarely goes over 8. But in my limited experience Allies need to go aggressive after Germany/Italy for it to work.
Either way, atm I'm having much more fun playing AA41 than Revised (which is also mostly KGF), so not everyone agrees it is broken

One more problem for KJF is the economic effect of NOs. It's arguably easier to take away both Italy and Germany's NOs than it is to take away Japan's. And if you have enough of a Pacific game going that you take away 1-2 ��� NOs, then you probably are allowing Western Axis to have 4, if not 5 of its NOs. In this scenario, Allies can have a decent production/IPC lead but gradually fall behind on Total Unit Value because of Axis NO income.
42 is the better scenario for KJF because a stronger China and weaker Japan allows Allies a good shot at the ��� NOs early on.. The rub is that Germany being an absolute beast makes this extremely risky.
