Daily Quest - Fire is a good servant but a bad master

It is weird that we don't find too many fire splinters own healing or self-heal ability. I think it is because fire splinters already have many high attack splinters so it should balance fire element's strength. No to mention that fire element is lack of magic attack. It is also for balance I thought.

Anyway, when I use the fire element to conquer my opponents, I frustrated for the battle result and take loner time to finish out my daily quest.
