Home court advantage in the Finals could be decided by whichever team got more first place votes in their conference.
Or when placing votes for regular season seeding, each voter will state the amount of games each of the first 8 teams will win in the regular season. Then when the votes are tallied HCA in the Finals are determined by who won the most regular season game votes, a number that could be a lot less likely to tie.
Also this same system could be used to determine seeding ties instead of having run off votes where the criteria changes and suddenly five teams are changing their vote.
