I mastered the precision mastery. It added 425 to the critical rating, but upon looking at my characters’ attributes to see if their percentages went up, I see that they have not.

Also, I do see that my attack is up. For example the green numbers went up.

Again, also, the regeneration mastery didn't add any extra regeneration to my heroes’ healing factor.

I added 5 mastery points to Lesser Precision. Yet my champions critical rating is unchanged.

My 4 star, rank 5, level 50 Ronin has a critical rating of 703. That is with Lesser Precision having no points
