5e /does/ have skills and the proficiency bonus, so it's not quite as character-independent as all that.
It has skills, but they're not the same kind of skills that Julius Caesar displayed. They're D&D-oriented skills like Stealth, Survival, and Athletics. There is no "Literature" skill, or "Political acumen" or "Horse-trading" or "Military Strategy". If such things were mechanically modelled in 5E at all it would be with raw ability checks, which are unaffected by any skills (unless you are a bard, so I guess bards make good generals). More likely though they'd be handled with pure RP.
