Totally agree. In MP, managing WT as a team is very important which means Japan attacking China is later but in SP it doesn't really matter much since whichever Axis powers you aren't playing are pretty useless. Hopefully the AI gets to a better place where managing WT in SP matters.The timing is a bit more delicate in MP. Conquering China is a large source of WT and spiking it too early is very bad for the Axis in the long run. Especially considering that Japan is probably the weakest of the Axis majors.
