I agree with 1,2,4 and 5 and have made posts many times especially day/night which is a game breaker for me to know they couldn't be arsed. Party size is dependent on campaign size even in D&D tabletop and I think the game map is cluttered enough at the minute with 4 party members, but of course this is my opinion.
My main issue is the addition of homebrew CORE game mechanics. BG is a D&D franchise and as such reflect that. I know Larian wanted to cut and paste DOS3, tweek a few numbers and hope nobody noticed but BG1&2 fans are where the money is as they are still alive and kicking. Tenny bops don't play games that involve effort, they push X and win, send a tweet then move on to the next exciting adventure.
I have no issue Larian adding their own flavor but the CORE game must mirror the mechanics already in black and white. I don't see how Larian can build a city like Baldurs gate or Waterdeep without a night cycle? They can't as most stuff happens at night. Random encounters when travelling between areas is a dice roll and a random map tile....too much to ask for? For those who want to play the story there are always easy mode and Larian are good at tweeking difficulty as DOS2 did it great.
The addition of "something" that competes with core game mechanics always has a cascade effect in D&D. Advantage and healing for example. Advantage is something gained though tactical positioning (or spell aka resource) of more than one character where instant healing is something class/spell specific. Monsters have their own playstyle mixing the fights up, 50 goblins is a slog but a lich, vampire lord etc. is a totally different fight, RUN AWAY!!! Time stop......boom dead.
D&D mechanics have nearly 50 years of ironing and tweeking I doubt a game adaptation is going to reinvent the wheel here. I will give it to Larian they are listening to the feedback but like I said earier no day/night is a game breaker for me personally and wouldn't of purchased EA if I knew. The game is good, could be better.
