Making unlearning free would be unbalancing. It would make utility skills like identify/pickpocket/lockpick essentially useless, because you wouldn't need to commit points to them.
Making it low cost would not be unbalancing though. It would change the game mechanics, but in a good way that would make for interesting strategies. Imagine spending 2000 gold to shift 10 points into lockpick, unlock a few doors, then shift the points back to slashing damage.

Well said. Unlearning has to cost something or it would have no point. You could change your charater to suit the situation far too easily instead of having to make do with the choices you've made, thinking your way around the game and maybe having to go back and remake your character.
Why not simply remove unlearning, and make the skills that are in
Beyond Divinity actually work? If Fire Missiles actually did good damage after investing 5 points, I wouldn't be inclined to unlearn the skill. Conversely, if you invest points in Lockpick and learn it doesn't work, why should you be charged to unlearn it?
