It is nothing major, but when I activate one "increase critical click chance by 3%" ability, the readout changes from 1% to 4%, but when I activate a second it changes to 6.99% instead of 7%. With a third in the formation, it goes to 10%. I have not tested it in all formations, but I do know it happens in the event, the box, and the jet formations. While it is not a major deal, I feel a little cheated, especially with the passive critical talent.
