It's not a good mechanic, but it's not necessarily a bad mechanic. It's bad when it's a bandaid, but it doesn't mean the game would be more fun with that "wound" left open, either. And in other cases it might be a mechanic that's nice to have with no good reason not to have it, but I wouldn't call it good per se.
In some, the game might just be designed specifically around offering respec in late/end/postgame, and since we're not talking MMO, a good chunk of the experience will still depend on the build choices you make throughout. But, well, it goes without saying that games should aim to actually explain what the fuck each stat/skill/whatever will do instead of accepting that you'll fuck something up first time as a given. It's fine if something like race selection affects your playthrough in unexpected ways - especially if the setting is new to you - but not stats.
