1) train fighting while attaking doors (destructable or not). It gives fighter or ninja lvl (bare hand attac or with a weapon). It was resonable. Using doors as a manekin

2) gain priest lvl's while warcrying. It was the easyiest way do teach spellcasting totally manaless characters at a very early stage of the game.
There was a joke: wonna be a priest? Then your good must hear you. Practice then

Why it's diffrent? (at least last time i checked it?) and:
3) why old RTC gamesaves aren't compatible
