Anybody knows how much reputation you need for all the ranks? I tried to keep track and am fairly sure that it's
100
300
600
for the first three. Then I felt like I figured out the pattern (1000 - 1500 for the last two) and stopped tracking, but it's definitely more. Maybe
100
300
600
1200-ish (unconfirmed)
2000-ish (unconfirmed)
Don't think it's visible ingame, but maybe somebody didn't stop tracking like I did after Rank 3...
