You may suggest that, but that's just not how armour works. Con ST don't matter for 10% of the time Dragonborn are impacted in combat through not having dark vision. Act 2 will bring A LOT more low light areas, anyone without dark vision is a liability. You can only artificially give dark vision to one person. So yes, that's not enough to save the Dragonborn. I'd be against a boost to all cha checks since, I'm sorry, but it just makes no sense to me. It reminds me of the argument that strenght should count for intimidation checks.
Like, what's going on here? You're taking my ideas in the worst light to just flat out shoot them down. None of my ideas so far have been especially eggregious, especially when, again,
they're just initial suggestions. Work with me, yeah?
It can be how armor works. Shield of Faith gives +2 to AC. Defensive Fighting Style gives +1 to AC. Shield gives +2 to AC. Actually, the Warforged (a direct race comparison) even get +1 to AC due to their armored construct nature.
Con STs are always relevant, as you never know when an enemy will cast an extremely harmful spell at you that requires an important Con ST.
For dark areas, you can always bring a light, cast the Light cantrip, cast the darkvision spell, or drink a potion of darkvision. By your logic, since humans and halflings will be a liability due to their lack of darkvision, should we give them darkvision too?
I didn't mean to imply that "all" Cha checks get a bonus. In the comparison example I gave, I referred to specifically Intimidation or Persuasion checks. We can also look at half-orc, who automatically gains proficiency in the Intimidation skill because of their race/strength/typical orc attitude. Why is this different than for dragonborn?
(Also, yes strength should be an option for intimidation. Bouncers often make use of this. People who can more easily do extreme violence to you are/can be more threatening.)
