There’s two things I think a bid should always be used for:
1 art in Kweichow - if you hit in Hunan J1, you can take down a good portion of the Japanese ground troops on counter attack
1 sub in SZ98 (the Med) or is it SZ99?
Others are mostly nice to have - 1art in Alexandria helps the the Tobruk crush, 1art in Sudan helps the Ethiopia crush. An art in Karelia helps the Finish push. 1inf in New Guinea helps to gain the NO.
