Ok, I was in hurry last two days, wasn't able to explain what I mean properly.
Let's see... the lack of blood and gore in Divinity 2 is explained by it's setting: it's a fairy tale. How much blood and gore do you see in fairy tales (well, ofc there are some crazy exceptions, but those just support the rule)? Just take a look @ Zandalor's comic clothes: starred robe, lol. The game has many similarities with Tarry Pratchett's universe.
The reasons of such setting.. well, I provided my opinion already:
age rating and
Larian's experience
