They are all perfectly reasonable examples, of the type that come up in actual play, rather than whiteroom theorycrafting.Sorry but those are truly terrible examples. The Dex fighter isn't one-shotting anything, that dragon should have been left alone or killed outright and what is the rest of the party doing if winged kobolds are an issue? Paladins must be terrible aswell, by that logic.
Dex melee is freakishly terrible compared to str and if this is the best you can come up with I think that point has been proven tbh.
The DEX fighter could one-shot a first level wizard, who could take out a STR fighter with Tasha's Hideous laughter. The dragon is too powerful to kill and is blocking the path to the plot-critical McGuffin. The rest of the party are outnumbered by kobolds because the fighter doesn't have a useful weapon.
And no, that doesn't mean paladins, or strength fighters are "terrible". This is the other Min-Maxer fallacy - anything that isn't optimal must be terrible - rather than accepting that everything has strengths and weaknesses that depend on the situation.
