I think there's a pretty clear disconnect between the power levels of the implied background of the PC and the backgrounds for the other party members. Like okay I'm a Paladin/Warlock who was apparently a Guild Artisan and there are occasionally dialogue options based on these, but generally I'm a blank slate normal guy; the perfect example of a level 1 character background.
Then you have the party members (massive spoilers)
- Shadowheart is an evil cleric who was probably kidnapped as a child but had her memories wiped by the memory-wiping faction she serves. She was doing some super important mission and should probably be higher than level 1.
- Lae'zel is a weird alien fascist who should probably be higher than level 1.
- Gale was a prodigy super-wizard who fucked the godess of magic, but now he's level 1.
- Wyll was a super hero warlock, but now he's level 1.
- Astarion is a centuries-old vampire spawn before he takes any class levels (Challenge 5 in 5e), but he's level 1.
- Karlach fought in the blood war, but now she's level 1.
Every single one of them (except arguably Shadowheart) are way too powerful in-setting to be a level 1 character in D&D.
