Specialists System vs Old School Classes (Poll)

I like aspects of both, the class system set the loadout and a purpose - Eng. anti armor.  Sniper/scout etc...   What I do like about the specialists is the 1 tool specific to it and the ability to use any weapon.   This came in handy in BF4 had when a map didn't have armor/air or was close quarters.   So I would like to see this.   

Not to be a old grump, but the 2 older characters really should be younger.  Something like Price from COD.
