I feel that this new rule isn't very fair, especially as the first player. You've pointed out two very important issues:
Increased Pressure: When you're the first player to get the correct answer, you face the pressure of other players potentially getting it right as well. If they do, you lose the chance to be the sole winner.
Point Disadvantage: Even after answering correctly first, your points can still be reduced because other players can also get the answer right. This makes your effort feel less significant.
