The Visitors

i wonder if we're going to see a weekly, bi-weekly, or monthly reset, allowing it to be permanent but constantly progressing. they can explain the re-occurrence by the maple world being stuck in a paradox, like the movie groundhog day.

Or they could be more logical and have there be invasion after failed invasion. This would also make sense with the crystonal time extensions. Miss it this month? maker sure to extend your equip in the chance to get it next time!

Also..... maybe the weapons and armors and such progress each time you complete a cycle. So say you have the 37 weapon, and next time around, it takes that and gives you the next tier weapon.... it would completely make other weapons and such WORTHLESS!!!!
