I'm annoyed as well that we haven't seen any major changes other than improved dice rolls. But it is still logical that Larian wanted to get as much done to get the game into early access and the hold off onto other aspects for later. So there are some Divinity hold-overs.
I don't know why RNG was the main focus, when disadvantage while attacking enemies on a higher elevation than you can confuse the player and result in a miss. (Note, this is not RNG's fault but a poor design choice).
That being said, where's a hotfix for rule implementation? If we can get a hotfix for different RNG, why not one to address backstab? etc.
For the record, there actually *is* a visual bug right now where your ranged attacks can actually roll for advantage, even though the preview tooltip doesn't show that you're high enough in elevation to get it. We think this might be evidence that Larian is tweaking some aspects of high ground advantage/low ground disadvantage... Or that literally no one cared enough to investigate closely until about a week after the latest patch.
