I'm thinking of implementing a different way of increasing player stats than just leveling up/completing quests. Basically, stats will be increased by the actions an actor takes in battle. Use a lot of physical attacks and atk increases. Use a lot of magic attacks/healing and mat increases. Receive phy/mag damage and def/mdf increases. Put your life at risk and mhp increases. Empty your mp gauge and mmp rises. Inflict abnormal status and luk increases. Crit/evade and agi increases. Use a lot of MP potions and mmp increases etc. Each type of action will have it's own level. When you gain enough exp (from total damage or number of times action succeeded), the action type 'levels up' and you get a parameter increase. Therefore, if you don't raise your characters in a balanced way, things could get very difficult as the game progresses. E.g. getting 1-hit KO'd by bosses. On the other hand, you can raise characters that are highly specialized in certain areas (an unkillable tank and a glass cannon). What do you think? Would such a mechanic make battles more interesting? You'll have to fight in many different ways in order to get stronger, rather than just spamming offensive skills and killing enemies. This includes using more support/curse skills and items, and doing crazy things like letting hp drop to low levels on purpose.
