Reset Masteries

Does anyone else think that in the masteries, you should be able to reset one mastery at a time without having to reset all at once.. This would be helpful by saving units and not having to buy cores again since you don’t get a refund for resetting the masteries.

Yes, but…

Evidently you have not actually done a Reset of your Masteries.
You DON'T have to use more Cores to unlock masteries again.
Once they are unlocked, they remain unlocked.

Only thing that it costs is the incremental Gold or tiny Units amounts for Leveling up masteries, NOT the bigger costs associated to “unlock” them again.
