Reward System Ideas

I have a few suggestions for a reward system I think would be great for the game. My idea is based on the skill taken to defeat the enemy and not just the rewards for defeating them. The rewards would change in amount depending on the difficulty of the event quest map, story quest map, star rating of the opponent, alliance war\quest map, what star arena and opponent you’re versing etc... each different part of the game would reward certain rewards for those accomplishments.
Arena rewards you with extra battle chips and gold.
Story quests reward you with extra iso and gold or potions and gold.
Event quests reward you with the chance to get iso or catalysts or fragments.
Alliance quests/war reward you with extra loyalty or potions or glory.
These rewards would be awarded to you in these ways that I have titled;
Untouched: If you win a battle and you have been able to block every hit from your opponent, meaning you have not taken a direct hit.

1%: winning the battle with either 1% health or you have only lost 1% health.

Combo rewards: the higher the combo you get the better your reward is.

Against all odds: winning the battle even though the likelyhood of you winning was past half way.
