Fixing some of the broken interactions, overpowered abilities and making every racial option appealing from a gameplay perspective has a benefit I think is very important: It opens the field for more varied characters without forcing people to intentionally play suboptimally. It would also give the optimizers more options for how they want to minmax the game, with more variety.
I don't see how making the game a bit more balanced would hurt anyone here. Isn't it boring to rely on the same abilities over and over when you're optimizing? I certainly don't find it very engaging that Haste is a fixed part of the solution to any encounter.
