Maybe more reactive system. If you often use an ability X, there will be higher chance that you will recieve a perk connected with X. Some examples:
- You start every fight by summoning elemental, so the game rewards you with "Summoner" perk - your summons have more health and/or deal more damage.
- Like to play with two-handed hammers? Everytime you fight with a hammer you have a higher chance of knocking back your enemies.
More general ideas:
- During the fight you tend to loose a lot of health. Your character will recieve one of these: health regeneration when your health reaches xx%, higher damage when your health is bellow xx%,
- Spending a lot of mana - mana potions regenerate more mana, your spells cost less mana
I think that it would be a great idea, because the player will be rewarded accordingly to his playstyle, not to his stats.
