Ji-N:
It actually doesn't affect the real rating or ranking, but only visually ATM.
Do you mean the bug about rating before airing or rating while a drama airs? If it is the latter, though some still continue to disagree about it, isn't it beneficial as a whole to take into account how a rating can fluctuate as a drama progresses?
I am not trying to start up this debate again, though. However, if you were referring to that, that the ratings of currently airing dramas aren't actually counted towards the overall rank, I do have a suggestion. There could be a seperate category of ratings just for dramas currently airing. Similar to how there is a Trending list, but instead of counting by list adds, it would be counted by ratings. It would certainly put to rest the perpetual disagreements about rating currently airing dramas. :p
Again, though, I only mention it atm if those ratings are not actually being counted.
