Dynia: Bard is clearly not for you, so maybe leave the bards posts be and stick to your overpowered party thread or however it is called. I'm on my second bard playthrough and they are amazing. They can cc, do a lot of damage and buff teammates. They are great in all speech checks and can be your Sleight of Hand character, if you don't want to have Astarion in your party all the time.
Sword bard get flourishes, which give them stuff like double attacks, mobility and more.
You are also talking mostly about melee, but how about you equip your sword bard with two hand crossbows? I do that ATM and I can tell you, that my girl does a lot of damage and even kill high level opponents in one round.
Lore bard with their cutting words can make all the difference in a battle, plus with magical Secret, the can get the best spells from all spelllists.
The point is, that bards can do all you mentioned above, which make them more versatile, than a pure caster or melee fighter or supporter. That is the point, they can be your get out of trouble card.
And the other charisma classes don't get the option to get expertise in speech skills, so yeah, they can talk with high charisma, but still a lot lower than bards.
As I said, you obviously don't really understand the class, which is ok, but don't come into the threads and try to scare new players away from playing that class, ok?
