Have a idea to make Mastery score useful:
-Like a leveling , for every 10th, 50th and 100th Mastery score to get some rewards. Idk what kind of rewards, can be champ shard or capsule, or some BE or orbs that's up to your creativity...
That way players can play more different champs and not just one (because 1 champ have cap on lvl7 mastery),mastering more champs and game will be fun too. (can be in way like missions, or leveling system)
Now Mastery score is just a number, but can you make it not just a number ?
Thanks for your time, reply for any more idea.
