I like most the changes made, particularly fire environmental damage, which is not in 5e but existed in previous renditions. Granted, I am a player that throws oil at enemies at low levels in 5e, so...
And I enjoy the bigger battlefields. Since I tend to play ranged characters I often concede the ranged advantage when playing 5e, otherwise I would start all open area encounters 600 feet away as soon as I get sharpshooter and nobody has time to draw maps that big/the rest of the party would be bored to death. In BG3 that isn't an issue. However melee does sometimes feel a bit dangerous, particularly since there is no dodge action (yet). But I think things will get better as soon as we get dodge and hopefully Strength based ranged/thrown weapons.
I do like that the enemies are much more dangerous than in 5e.
The shove as bonus I am not sure I like, it's nice, but I'd rather it was kept as an attack.
Jump/disengage is very strong, but I do feel it speeds up combat, so I am all for that.
That's my take on the changes at least.
