As the staff have said in the past, Mayor was originally intended to be a hidden weapon. He would reveal later in the game to re-gain the lead or pull further ahead in general.

But then Mayors began revealing and asking players to whisper roles.... So BMG removed the Mayor's ability to send whispers and receive whispers.

Players got around that by taking the role of Mayor by being a confirmed townie. Players would vote up as many people as they could to make the day go for as long as possible. "Everyone, quickly vote up one! GET ONE'S ROLE!" This strategy strongly benefits the town.

So they've reduced the amount of trials to a maximum of 3 per day. Less time for townies to gather and spread information.
