95% of players will only experience a match or two at most. Increase the recharge rate, and you will lose far less players. 1pt per 10 minutes would be a relatively small change, but keep the game more worthwhile to players.
About Auto-Upgrade: Check your Blacksmithing skill for "Won't disappear before +_". Auto-Upgrade will let you upgrade to that safe level in one click. I assume that it costs the appropriate amount that it would take. Also, I think it would greatly benefit the players to have more information about the current monster in the mostly empty monster panel. It might help explain why you occasionally do 1 damage repeatedly to a monster like "Weakest Young Gray Fox", and if and what the monster's title bestows. Explaining if there is a difference between Armor weight would be nice as well.
