Larian has masked the BG3 system to be similar to Divinity in a number of ways.
Backstab being guaranteed critical for finesse weapons in DOS2 = advantage in BG3
High ground providing extra range and extra dmg in DOS2 = advantage in BG3
Abundance of haste potion, haste spore flask = subsidize BG3 limitations by giving 2 attack action (equivalent to 4 AP standard in DOS2)
Wet + Electric stun in DOS2 = same in BG3
Wet + Cold freezing water for slip/knocked down in DOS2 = same in BG3 (just re-named to Prone)
Disengage/Shove/Hide being bonus actions = subsidize BG3 limitations by essentially granting more AP per turn (4 AP standard in DOS2)
Unlimited Long Rest without penalty = spells always available before every fight and no resource management for spellcasting (DOS2)
Any class casting any scroll = DOS2
The most effective way to navigate Larian combat is still the same. Use the shared initiative to burst down 1 or 2 enemies on the first round of combat and snowball the number differential from there, bolstered by free advantage and jump/disengage cheese.
If you consider that Disengage/Shove/Hide and other things on bonus action, which should be an action, is 2 AP (the equivalent of 1 action in DOS2) and the full action each turn is also 2 AP (the equivalent of 1 action per turn), then you have 4 AP a round.
The only thing that changed is you had to add Concentration mechanic and a higher chance of missing spells due to 5e AC and DC mechanics (that Larian has attempted to minimize by lowering AC, giving low-effort advantage in abundance, and offering 0 penalty for blowing your spells each fight).
It is clear what they wanted to do with the game.
If only they could be open to other mechanics than the ones they use in their own IP. There is no *one thing* that only works in a video game. BG 1&2 are good games, Pathfinder: Kingmaker is a good game, Pillars of Eternity is a good game. And all of those games are better games for me mechanically than Divinity Original Sin 1 or 2.
Is it a fact in the game industry that a game with a AAA budget has to be "dumbed down" to find the lowest common denominator in players. High production values but shallow boring gameplay? That's what happened to the Dragon Age series.
