Change speed so that your speed subtracts from the enemy and the remainder is multiplied by 2 or smthn and thats the percentage change. Also consider making talk options exhaust so that they are one time use. Also instead of the enemies stats scaling when you don't damage them you should just make all their stats (power, defense and speed) scale by like 0.2-0.25 every turn to encourage strategy use.
