Huh... interesting. Perhaps I haven't seen that level of specialization take over, or maybe my players haven't been as good at it, or maybe I just run a slightly different game than your narrator. I am kind of curious to see how I handle that sort of super-specialization, because in my games, it's tended to be more hindrance than benefit.
Most of our characters have a 4 or 5 in their highest "stat". Our knight has at least a 4 in weapons (plus some specializations) and must have gotten at least decent scores in Athletics and Endurance. My bluffmeister has a 5 in Deception (and a 1 point specialty in Bluff and 2 in Disguise), and our most recent PC (joined a session or two late) has Archery 5 plus a specialty point or two.
So in my character's case, when I want to roll a Bluff, I roll six dice and drop the lowest. It ... adds up.
Our group generally consists of older characters. My own character is middle-aged, although he's so good at disguise he often appears much younger. Or older.
My bluffmeister got forced into combat once (the one where our knight almost died). He fought a bandit with 4 weapon dice. Fortunately, he was disguised as a mercenary*, so the bandits didn't focus on him like they would have if they'd known he was a noble

We learned we only needed to worry if the deck was heavily stacked in the enemies' favor. (They ambushed us, had slightly better numbers, were kind of far away, uphill so they were hard to get at, were hiding behind cover, and yet our knight still killed more than half of them by himself -- at great cost, but still -- and even my non-combat character found it safe to get into melee with bandits so he didn't need to worry about being shot at by other bandits.)
Even generic NPC bandits have a 4, for instance, those archers that basically killed our knight had 4 in Marksmanship and the melee bandits had 4 in weapons, but generally had less stat backup (I rather doubt those melee bandits had the 4 in Athletics required for high damage).
*How'd he do that without armor? Neither the GM nor I noticed that until afterward

And yes, I'd like to know how you handle this in your game. I could pass tips to my GM.
