Being able to respec your character is now so common in RPGs it would actually seem weird to many people if it wasn’t there, there would certainly be a lot of demand for it. Not sure whether there’s a cost to dissuade people from doing it all the time, which is pretty normal.
Respecing the companions to a different class could cause issues with the story and interactions. Presumably it’s some added flexibility for people who want to play with particular compositions but don’t just want a bunch of mute mercs in their party. So if you’re happy for the game to treat Gale like a mage for the story, but play him as a paladin or something in combat then that would be a option. If that’s going to bother you, best stick with defaults.
The multi-class thing could be more of an issue if it makes them too OP. Hope they don’t screw it ip.
