Galactic Wars Ability Materials MK III

Javofett

I just noticed that the last 3 battles ( sometimes on the last 2) in Galactic War they give you One Ability Mat MkIII (Purple)per battle. But once a week, I have gotten 2 Ability Mat MKIII (Purple)) per each last 3 battles. Is it because I am very lucky or is it because the way I played (not changing team or prob I won fast) or Is it just intended to be like that per devs?.

Thank you in advance for your guidence.
