What you were expecting to happen, and what actually happened:
I play arena only for dailytasks and note in the match before that a single 3 bluematch giving 3 instead of 4 mana. So i look in the next fight whats going on and check the weapon and banner and choose it. But it helps less.
How often does this happen? When did it begin happening?
First time for me.
Steps to make it happen again
I don’t know.
