Post 5.1 we get the nameplate "parts" like this
Code:
local barFrame, nameFrame = nameplate:GetChildren()
local glowRegion, overlayRegion, highlightRegion, levelTextRegion, bossIconRegion, raidIconRegion, stateIconRegion = barFrame:GetRegions()
Could anyone tell me when highlightRegion is shown? Tried to test this myself and it seems it shows sometimes when one places the mouse over the nameplate, but most of the time this didn't happen.
