TypeRDC5, yup, barracks explains things..should of spent a little more time looking in there rather than playing non stop

. You get another token when or if you do prestige, but it will not give you an extra slot for a class. So you have a choice on how you want to use the token....arghh. Well not that I needed an extra class since 5 is plenty already.
As for HC TDM, nah...rarely see any one with 2.0 K/D for a total game play of 1 day 14 hours of play, but it is mixed between -1 to 2.0. No mini map which is nice and takes only a few hits to get kill, but same goes as to dying or living.
SmokingCones, yeah if you want to get all the guns challanges sooner, dont prestige. They added I think 20 extra kills to each attachment, plus the hardened challenge~!
The two good things are that you get to keep all the Title and Emblems. You do not have to go into the regular mode at all and can access HC without leveling up.
Feel bad for who ever played with me for the first hour. Went from 1.78 to 1.59 and finally stable at 1.59 on HC TDM...so I died alot!!!
