I'm getting an increased number of "WARNING: Too many characters matching..." errors when Census+ is trying to take a poll of the lvl 60's when there's, for example, over 50 Night Elf Rogues at lvl 60 whose names start with A.
Since the servers seem to have an overwhelming dominance of Night Elves and Humans, those are the two types I'm seeing this the most on.
Since the processing is limited to 50 a go, I'm sure you foresaw this... what are your thoughts, oh wonderful Rollie?
