I feel that stamina needs to be less restricted. Either increase the amount of stamina we get or decrease what things cost for stamina. I've been stuck at the same level for a few days now because I don't have stamina. When I get stamina, I use it for things like the labyrinth and the heroic realm and things of that nature so that I can get what I can out of it as auto level up is a useless function when you get to level 50. There's no reason for enemies to cost one stamina for every battle with the auto level up because more often than not, because my character is at the level it is, there is not enough experience to be gained this way to get to the next level because of the lack of stamina. I also agree that stamina should be refilled every time you level. Most games have this, I don't understand why this game is so limiting. It doesn't make it more challenging, only more boring.
