Exploit question

[Illuminated One]

When Shift-U-ing things into a real battle you will also see that the enemy mages will use different spells. So you can practically get to know almost the whole research of your enemy if you shift-u a lot of different stuff into a battle and note down the spells your enemy casts. This is an exploit imo, but I suppose many people know it already, so it's probably better if everyone does.
