Narrative flexibility is nice and all but your commenr mentioned representing any archetype. I'm pointing out it's a mechanically weaker representation.
The hit die doesn't make a big difference because CON bonus moderates what is only a small gap to start. (1hp+1hp/lvl). Better AC (shield spell) > those hp.
Bards are great for flexibility in building them and definitely got a lot going for them, but when it comes down to a direct comparison they fall behind focused classes.
I'm saying representing talent and training doesn't make them better than either sorcerers or wizards as casters. That's an observation, not a fight.
