Extra crowns after pass royal is complete can be converted to something useful.
Either gold, gems, season tokens.
It doesn’t have to be 1:1 but there should be something you are saving for with the extra crowns….maybe after you have a bank filled with x number of crowns they can be traded in for a shard or a royal king chest?
Seems like a no brainer and it fits in nicely with the business model of getting players to continually play.
Mastery tier three masteries are useless for the amount of effort needed to achieve them….make them something special….likewild cards, tokens, or shards.
Thank you
