Konnichiwa,

Part of the 1.03 balance was to counter 'super'units due to upgrading/downgrading. MTW has a better upgrade cost system, so that's no longer an issue (missile discount is an exception). MTW charge seems more effective than STW's.

I wouldn't say that monks are better protected against arrows because they have the required minimum of 1 instead of 0. Arrows seems more effective: it was a mission impossible to kill a kensai with arrows in STW, I've seen him die many times in the first volley here (there are also AP Longbows around in this mod, halving the protective armor).

A 100% accurate port of 1.03 STW data to MTW will not give the same thing.

The opposite may be true. The nagcav and no-dachi were fine units in STW because they were 'cheap' to upgrade. There may be other things, but that's where they lost now.
