I don't think the first time I read this reply I could truly grasp what you were saying, so I waited to reply. Now that I have dabbled in a a number RPG maker fights of my own making. Now that I have played with the monsters, and re-red the tutorial comic a few times, I can see what you mean.
I aim to give the monsters a number of weaknesses and strengths to force the player to make strategic decisions as they go along. Defense, offense, attacks both physical and 'magical' are all things I want to use to knock a player off balance and have to think on his or her feet.
What I now also understand is that I'm going to be play testing these fights for weeks to get the balancing right.
Thank you again, this answer gets more helpful the more I comprehend it!
