[suggestion] let players know how arena progression works in-game

I remember when i first started playing, one of the most frustrating things was being bumped up in arena to a league where i could only win ~30% (or less) of my battles. The only way to figure out how arena progression works is to find this forum and then find a post from like a year ago that explains it. If there was an infographic somewhere in game that explained “when you surpass x power level you’ll be bumped up to y league” it would be a huge help for new players so they don’t accidentally find themselves in a league where they can barely win any battles before they’re ready. I suspect this problem occurs for many new players and is very discouraging, a simple graph in-game showing the relation between team power level and arena league would be super helpful and a great & simple way to retain more new players.
