Bronze reward for leveling up
Bronze is one of the bottlenecks of the game, and hard to get. Opening chests and crafting drains our bronze and makes saving up harder. Especially after K5 and K6, we need a lot of them, and the only way to collect it is from Kingdom Bronze Bank (some can say we can also get bronze by battling and reaching battle milestones daily, but the amount we get is not so high.)
As a solution, I think we should get bronze (and maybe some rare resources) once we level up. This will make leveling up more meaningful. Currently, when we level up, we only see an increase in our combat stats.
