The problem is with the game (sim), pro's would be wedging all the time if it was more efficient than using the putter just as we would be putting from off the green if the sim worked as in RL.
The game is not a perfect simulation of golf but it would be a bit closer if using wedges on the putting surface had a bigger random factor thrown in so that putters always had the advantage. Until that's done though it's the players choice.
