I still dream about small switch button!^^

Well, as you said, no changing vanilla gameplay is great, not changing rest of things (by built in game button) is even greater. Is there any way to small button to switch in mod between Vanilla menu Background + Music intro and EF menu Background + menu music? And one more question. Are tanks of enemy getting bigger hp in EF as we increase difficulty? That was the most stupid idea in Company of Heroes. It completely broke realism of battle. I remember when I played Axis, and my superior tanks ( Panzer IV and Panthera) had problems with beating Shermans (which was strong as Tigers, to destroy it you have to hit is so many times) with insane hp on high and very hard difficulty. Is mod follow this awful idea? I think higher Ai should be wiser CPU, alternatively cheating resources. And one more question. Is Jioesph Stalin tank weaker than Tiger Tank? because there is posibility to build many of them, which seems unfair to fact, that superior tanks like Pershing or Tiger are limited to 1.

Yes, the mod follows the general flow of vCoH - same tank/infantry combat.  Sorry to hear that you don't like that. :( But I nonetheless enjoy it.  The mod does give some better AI for the computers, although it's far from perfect.  The game would be way too easy if more resources weren't given to it - it's just impossible to mimic human functions with pure code.

No,  I like cheating AI and AI improvement in mod. I only dont like unreal tought enemy tanks on hard and very hard.

The health buffs the AI got should have been removed.

AI does get somewhat more clever and aggressive the higher the difficulty, but code can only do so much. And this is made even worse by the fact that Relic disabled debugging for the AI, which makes working on the AI code extremely difficult as any little error will have you spending hours trying to find it

Is it possible to test the AI code in older versions then apply to the current version?
