It took a lot of grinding - one hour every morning before getting ready for work and getting the kids up for school, and several hours early on Saturdays and Sundays before the family stirred - to reach Rank 4. To receive a single pair of Legendary gauntlets for it is pretty insulting. In fact, the gauntlets I received for reaching Rank 4 literally slapped me in the face. THAT'S how insulting it was. Did anybody get anything better than a single piece of Legendary racing gear? Are you going to grind to Rank 5? Edited for accuracy.
