Just to add some fuel to the fire:
I recently finished up a campaign playing SSSR with current version of DH 1.04 WIF2, tried to play as historical as possible.Seriously the amount of IC germany has is obscene and not just that.
1) Declates war in may 1939-beats up Poland + takes Strasburg from France and slowly grinds it down (there was a complaint against that recently, forts=useless)- I unfortunately signed M-R pact early. AI went apeshit probably because of this.
2) When finally 1940 Attacking the west decision fires, Germany has a serious advantage in everything already. IC is around 450/360 and France(what´s left) and Britain have IC around 350 together. Having no serious military against Germany.
3) Germany attacks me in 1941 june(ok with that) it has effective IC of almost 650 ( with Speer still coming in ´42) I don´t even have half that. It outnumbers me in everything + events that make me loose airforces, hamper my combat ability and IC maluses that go off to late.
4)Now I liked the challange but since DH is quite IC and number based, you simply cannot go against almost 1.5 number seperiority, 2x the planes and almost 30 Panzer divisions + allies, in a current setting. I know it´s partly WIF2 event based stuff, but by playing DH 1.04 vanilla it´s even worse.
5)I didn´t play gamey or used militia+infantry spam early on so I was expecting a fight here, yet I was overwhelmed in early 1942 in basically everything. I don´t dislike the challenge just to note that playing Germany as a human right now, is pointless, you can dominate everything.
Only difference is that SU AI gets some free units, hardly enough though to stop the tide, also some morale boosts. But those are not much against the Germans.
Combat wise: Also, seems to me that armies do not loose organization when moving as much as before. Noticed it in China and with Soviets, this helps Germany tremendously in the East. It´s already strong, but this helps when crossing those hundreds of miles.
Armies tend to get destroyed by encirclement a lot more often I think that further causes collapse in the East, positive thing is that AI does encircle or tries it a bit more.
My setting: aggresive AI/ normal difficulty
no IC/ tech takeover
no free wars
