Visual indication of PVE mission stacks

Infrared

Each event PVE mission can be played several times (five seems common at the moment) before its "stack" is depleted and its value is reduced to 1 point. The stack refreshes after a certain number of hours.

Suggestion:
On the mission selection screen, there are animations of rotating circles around each node. There are also 3 small triangles on the outside of each circle. Make the number of triangles represent the number of plays left in the node's stack.

It would be nice to also state the refresh timing in the event rules page, which currently has very little to do with actual rules.
