you can also get rank reset if you are a big time 'NAUGHTY' player
example the first wave of inheritors were all big time AFKers, there first ban was a rank reset.
So if your a big time cheater/booster/naughty person you will more than likely go straight to reset
Has to be Elies as they are the most honorable species, when the truth came out they did the right thing.
Least favourite species jackals/skirmishers why? have you played skirmageddon lol
Hopefully your rank will return once everything is back to normal
On a side note I've lost 100,000cr off my total rank up amount so now less than halfway to noble
