I am very competitive and would never be able to use this feature unless I felt I was gaining some form of benefit from it.
I am willing to play weaker players but my brain needs to know that they are weaker. Because its possible to still improve playing weaker players providing the right adjustments to how you plan to play the game.
So I try to take away something no matter what and I feel the unknown would prevent me from taking anything away from it.
Some people might benefit from it though I can see how they might benefit from it. My competitive mind just wouldn’t allow it :-).
