Ya I like it too.
2 inf = A2 A25.0% total
1 inf+1 art = A4 A50% total makes up the drop for sure.
Cost ya 7 instead 6 icps.
Do you know how many Art are bought in a game on average for China ?
I hope it will be at least Arty A3 D2, so chinese Inf will get A2+A3 for 5/8 or 62.5% which is nearer the OOB 4/6 (66.7%) combined arms.
This little case also shows that China might be better with a strong Arty A3 D3 because defense 5/8 (62.5%) will be nearer OOB 66.7% for Art+Inf.
Otherwise, 50% 4/8 combined defense is a whole D6 pip below OOB 66.7%
China need something because japanese Fighter and TcB keeps their usual OOB 50% attack per unit.
Interesting idea about Chinese Inf at cost 2.
Mostly the case with AA50.
