That's not quite true.
With my combination of many modes for TMO_RSRDC_OTC (including Toccos Revange) the hardness of the opponent is again set to the level of TMO, without the annoying radar error with the Japanese and the excessively many aviators.
RSRDC is a wonderful campaign, if you stick to its commands, there are also no problems.
Whoever says something else, talks only crap and has no idea.
