I had the same concern as OP and that's something I fear since tje first gameplay reveal with dragons and explosions in the intro cinematic...
There's nothing more dangerous we can find and again, the game is gonna be more gamey than really consistent inside the reality of D&D and the FR.
Everything will rely on the creatures levels which is just a gamey concept and creatures that are supposed to be very dangerous (or the most dangerous) will be ridiculously weak.
Again, it looks like they picked and dropped "cool" creatures everywhere because they consider it's not fun enough to fight more usual (and weaker/less impressive) creatures...
This is totally something I hate in Larian's game design.
Everything is supposed to be special... But nothing is really special, impressive and interresting anymore after a few hours.... The level of "amazingness" reach 100% after the first hours and nearly nothing look epic anymore.
Its not even about the difficulty level. Its about how the world feels. In BG3 the execptional is standard.
Exactly this...
