If yes, we introduce a bias so that people know which rants are doing well and might then feel like they too should like them.
If no, we make it hard for people to relate their actions to an effect. For example, I just applied an item to an enemy rant. What did it do? How did it harm that rant or help me?
If no, it makes the contender power graph more interesting. Because now there would be some strategy to determine which rant do I THINK has the top power.
If yes, will it discourage people with lower power? If the point is to get people to engaged, do we want to tell them they have no shot in hell of winning? But the flip side of this is that we might encourage those that are close to winning to become even more engaged.
If yes, this kind of breaks the potential gambling system. We'd have to come up with blocks to prevent people from placing bets on the top rant 5 seconds before the timer is up.
If no, will people get really frustrated with not knowing their place? People will want to know how close they came to winning even if they don't win. And they might want to know which rant came in second place today, not just the winner.
