Individual class ranks

Just an idea I was thinking of would to be able to have each combat class posses it's own rank.
Example: Police recruit, Private. Get a certain amount of BP, kills, or xp levels and you become a Police recruit Specialist or Corporal. The rank is only for the police recruit, as all the other combat classes start off as private or a first base rank. This can encourage more players to get in the combat more and encourage more variety of playing various classes. The rank tree will have to be formulated, but once a player has reached the highest rank for that class, they could possibly be given a big bonus and have the option to stay there or reset back to private. I'm not trying to bring in call of duty aspects or some crap like that, but this would be like a nice lil' thing people could enjoy. If it is not wanted that higher rank classes have benefits, then the rank system can simply be cosmetic and still have an equal start as the private. Let me know what you think, thanks and have fun.

so basically permanent ranks for individual classes?

Maybe, but if I did that, I'd probably remove level ups as a result instead

Or maybe just to say "Hey look at my cool rank meaning i'm good"

Yeah, I like it.
Nothing else to say...
I... Like... it...
