An analogy: Amazon is $1k/share today. Let's say you think there's a 30% chance it will 3x in the next year. Would you like to invest at $2.5k/share today? The answer is No because that has negative expected value, and you'd rather just wait a year and invest at $3k/share than investing at a small discount to $3k/share today when the stock is worth much less than that.
Also, the time horizon doesn't change the misaligned incentives here. Because I get in at next round's price, I would prefer for that price to be lower.
