Thought on Sweep function

I was excited with the "sweep" function to clear stages fast. Then, the requirement to perform "sweep" for the evolution dungeon was "Guardian Level 76." The requirement for sweeping the resource dungeon is "Guardian Level 26."

"Guardian Level" does not mean your hero's level. It means the level you reach at "Guardian New Base." So, it will take a while you reach level 26, and much longer for level 76. It will be an extremely long journey to be able to use this "sweep" function at dungeons.
