If you don’t like it, don’t use it. I haven’t, but I’ve completely ruined my build in other games and wish I could’ve respecced a little to save myself a headache. This is really a non-issue. I doubt people are using respec as an auto-win button. It’s probably used in two cases:
-Build experimentation (because who wants to replay a whole game just to know if a character concept works)
-Serious errors made in build development (someone fucked up and needs to hit the undo button a few times)
Nerfing respec sounds specifically designed to punish newcomers who might make serious mistakes, all in the service of making an optional feature less annoying to people who were never going to use it in the first place.
