I dont mind if the game become harder. Actually I think it would be nice.
I do have some thoughts about it:
I don't want the game to become a lottery, having some shots that react normal and some others with not wind applied or going shorter or longer (like actual US Open qualifier). This said, I want the game to be based on skill, If we make a good shot then the result should be good, a ding is a ding.
In order to do this, I believe, messing with deviation and precision is not the solution. To have a harder game WGT need to implement additional stuff to the equation, like stand control, draw and fade in every shot, hair in the green, wind affecting putts... and a lot of more things that can make game interesting; letting the skill to play the game and not a random set up to each round and each player.
