Arena suggestion
Hello. Hopefully there could be some changes made in arenas to ease the workload(a little bit) to those players who rely on grinding arenas for resources/featured and basic champs. Etc.
-Could be made simply by putting the used champions everytime you finish a round at the bottom of the rosters.
-Then add a "Help all" button on the upper right side of screen in arena section
-Make an option to put the filters made on lower rightside permanent until toggled back, since other prefers to just use 5 or 6*s if only going after milestones.
