I checked the overall logs for frost mages and I am currently rank 32 out of 1,626 frost mages. That’s in the upper 2% of all parses for frost mages. Maybe im thinking about it wrong but would definitely like a response
You’re looking at your historical % (how the rank looked when there were only 22 parses, early in 7.2). Today’s % is a 98% as expected. Switch to the Frost tab to see that more clearly (the Ranged tab is pitting you against Fire and Arcane mages as well).
Historical % is the rank position around the time the parse happened. It’s not a very relevant number when there aren’t very many parses yet (as was the case in the parse you are pointing out). Nothing is “decaying”… it’s a historical number, from the day you did the kill.
