In orthodox Chess there are also end-games that require more than 500 reversible moves to force a winning conversion. So going to an 80-move rule there doesn't really solve anything. The end-game that would probably be affected most would be KBBKN, which is generally won with an 80-move rule, but mostly draw with the 50-move rule. But it is very questionable if it would be a won end-game at all on this larger board.
