What am I doing wrong???

[Miles Teg]

OK.
I am playing long campaign as Germany.
I wished to start with custom force so for the first battle I gave myself 65000 resource points (overkill?)and bought Panzer KP, Pz Grenadier KP (dismounted) and some support Mortarts. After this I changed back to XXX resources for both me and opponent.

After 5-6 decisive wins I moved to France with the same results.

But when I came to North Africa I noticed that opponents (Anzac and GB) are fielding an ever increasing number of units.

In one delay I was faced with over 300 units!!!

Now, most of my forces are veteran and elite but there are only 60-70 of them (I bought some Stug's, mobile AT 88mm, and some arty.) and are having difficult time with the onslaught of so many of enemy units.

I understand the priciple of assault, advance, meeting engagement, delay and defence and the percentages it carries, but I find them a bit unfair since the AI is buying only low exp units and because of that can field not only 2x my force but even 4x or 5x.

I would like to keep my original units during whole war, but if they keep increasing in exp there will be time when AI will be so numerous that I will be defeated.

So, why unit cap isn't applied to AI, too?
Or, why isn't AI tweaked so he can buy experienced units?
Or, is there a way to avoid all this (I tried giving AI manual resource points but it looks like cheating)?

Sorry for long post.
