Maybe one way to fix the stamina bar from always being empty is to maybe fill up the whole bar every time we level up. At higher levels, it is already hard enough to decide whether to spend stamina on upgrades, quests, grinding, labyrinth or countless other activities so it often just leads to most players just afking and waiting in the city (causing lag) until stamina goes up. Personally, I think that at higher levels if you can get the full bar of stamina it would be a more satisfying accomplishment rather than just the endless cycle of waiting. Thoughts on this?
