Dragon Age Origins did choice and consequence right. For example if you kill the mages the templars join your army, or if you wipe out the elves you get werewolves instead, etc. Big one near the end of the game is that you can recruit Loghain at the cost of Alistair.
Now look at the choices in BG3, wipe out the tieflings? Lose 3 companions, 4 if you can't convince Gale to stay. Lose quests and vendors, miss out on one of the best pieces of equipment in the game. And in return you get Minthara who is essentially a glorified hireling with bugged dialogue. Kill Nightsong? Everyone in Last Light in gets fucked, lose Jaheira as a companion meaning you also lose Minsc as a companion in act 3. Try to team up with Gortash in act 3? Doesn't matter, gets killed anyway so the game can railroad you back into the way that Larian wants you to play. These aren't choices and consequences, it's you getting fucked over because you dared decided to try and roleplay.
Thats a good thing, people complain that game i easy, and they can play evil and make game harder for themselves last light fight was a lot challenging in my evil playtrough first you kill normies then they all resurrect, and you have to kill them again
That fight was a trash mob fight. Easy fight on Tactician. The only difficulty is if you want to keep Jaheira alive which you might as well not even bother because she's just going to ice storm herself to death anyways (the canon end of her character arc).
As far as the "best pieces of equipment" mentioned, there's only two or three really worth getting there and it's not a big deal if you can't get them. Besides, you can fix that problem easily:

It's not cheating because it's your computer therefore your rules. It's roleplaying because the guy only has it because it was left in the forge in the city. No way he's creating all those items in the time it takes to reach his shop given that he should be reaching the city around the same time you do and no way he has the time to make it while traveling. Also Legacy of the Masters is a BG1/BG2 item, it should be available in game to anyone who finds it or it's not in game at all. Besides, not getting those items isn't a big deal.
