I couldn't agree with you more but mention this relatively recent practice and up they come...I call them opportunists . They've long recognised this imbalance and have they exploited it!!!
Why spend years, as many have done, to properly read the greens and steadily perfect your putting skills when suddenly, you can throw any shot onto a green and not worry about distance from the hole because WGT allows you to chip your shot, and having perfected this, no worries about borrows, dips and the like, just chip it.
But you dare to mention this imbalance and wait for the snarling teeth and dripping gums. The baying of the hounds screaming abuse.
Why? Because these people are the win at all cost types. The idea of fair play genuinely doesn't enter their minds.
When WGT themselves realize this imbalance and do as you suggest just you watch these people struggling to maintain the position they presently hold.
There are of course many excellent players who don't resort to this tactic but a considerable number who do.
