Hmm, that's a tough one to answer. To me, personally, it feels much just like adjusting a few parameters that do not change how I behave inside the game. I'm not changing my gameplay style. Unlike, say, an ability skill-tree maybe would make me. So for me it did not really do the thing - but that may be a very, very personal impression! 😉
I basically just pushed firerate to the max because that made the game most engaging for me and then played a bit with the health stats.
