2016:
Although I'm no super fan of juries I still see their point, I would maybe change to 60/40 in favor of the public though...
The ranking system is tricky, now that the public vote is having its fair share its negative impact is not as big as previous years, but then again the juries still manipulate results by putting some countries last on purpose (and not by objective judging), on the other hand ranking all means that they need to put more attention to each entry and I feel like an issue was that juries didn't pay as much attention to the songs but more to vocal gymnastics etc because they never got the time to build a proper "relationship" with each song. I think the jury process should be longer then, every member would have to listen to all songs carefully and not just judge on the jury finals because if only the latter the songs become secondary, when they should be the most important. Also more members in a jury group would make up a fairer result.
The spokespersons should give out the 8's and 10's like previous years, only giving out 12's felt too rushed and suspense-killing and quite frankly doesn't save much time but instead takes away alot of the feeling from the voting process and makes it slightly confusing and more difficult to follow for the average viewer.
Pay equal attention to all sets of votes from the public. Again it wouldn't take that much longer, but atleast make the public vote look equally important. It felt a little too rushed aswell.
2013-2015 were dreadful, the juries could easily manipulate the outcome, thankfully 2016 erased that aspect and made it more balanced, now atleast public's favorites will get some points even if the juries disagree and can't be totally erased by juries. Also the new system is as close to 50/50 you could get, which is only fair.
