A total of 2,036 players voted and of that 515 liked the update, compared to 974 who preferred how the game was before. This means of the players who either liked or disliked the updated, over 65% preferred how the Bounty Board and PvP Ladder used to work. Or if you include the players that didn't mind along with people who disliked the update - it would give a total percentage of 74.7%.
How can you lump in the "I don't mind" votes with the "No" votes? It seems to me that "I don't mind" is closer to "Yes" than it is "No", as it means "I don't positively like it, but I can live with it" as opposed to "I don't like it". If you add the "I don't mind" votes to the "Yes" group, your numbers come out quite different, as it would make the "Yes/Don't mind" vote 52.16%.
Subtracted out numbers provided to get the "Don't mind" number.
Also, your 65% number is only including the "Yes/No" votes in the total, completely disregarding the "I don't mind" voters. To me, this seems like skewing the statistics a bit by completely eliminating one of the voting options.
