Knytestorme it has been my experience that points roll over well before the servers go down for maintenance.... ie hours before (which i always found funny on maintenance nights to see teams trying to pug their 10 games in and the points already rolled over....

either way if you are certain you will have enough points i'm rather certain that you will be able to buy the gear before maintenance (well that is if you are willing to be awake at ehh what 5am or so CST
