Cause serve becomes like every other shot, if you make 1 mistake its a point for your opponent. They still have advantage but we wont be watching ace fests.
That's really not gonna happen. A top player capable of boosting a powerful first serve will diminish his serve by let's say 10% to allow himself to keep causing trouble to the opponent's return, and will continue to serve aces most of the times. It will be worth any risk. I dare say they would become even more dangerous.
The weaker players with imprecision in a powerful serve will be forced to diminish their serve by much more, basically casting a second serve each time. The opponents will use this weakness against them and win even faster.
The players you call "servebots" will perform even better, while the players with a powerful, yet unstable first serve will suffer, despite their game being concentrated in other areas too.
This move would transform ATP into a WTAesque type of tennis where most of the games are breaks.
