We discussed in our Play Testing Group a few minor changes to the Basic Expansion - one of them was the cost reduction of the Waffen-SS Infantry unit.
The main reason for this change, is to avoid confusion when players go from Global 1940 Basic Expansion to the full capacity of the Axis & Allies Global 1940 House Rules Expansion.
Concerning Play Balance in the Basic Expansion, it doesn’t seem to have any major influence - mostly because players only use the Basic Expansion 3-5 times before stepping up to Axis & Allies Global 1940 House Rules Expansion.
A few more changes to the Global 1940 Basic Expansion might come within a few months.
