Not really.
The only people complaining against the turn-based combat were a small minority of people who begurdged the fact it wasn't so in BG1 and 2.
Personally, even as a fan of the old Bioware titles, I found the passage to turn-based arguably the main NET improvement Larian introduced to the series.
What? No.
There was TONS of feedback about how people weren't interested in CRPG's but gave BG3 a shot and ended up liking it.
It's how it managed to receive critical success despite CRPG's being an incredibly niche genre before BG3.
What? No, it wasn't. DOS 2 was a massive hit and it sold almost 8 million copies in a genre where most of the competitors would be ecstatic selling few hundred thousands.
A lot of people who never cared about the BG series in the past (their loss, really) were thrilled about BG3 because "it was from the same studio that made DOS 2".
What are you going on about?
Larian, and Swen himself, has mentioned that DOS2 didn't perform as well as hoped.
Also plenty of people did not care about DOS2. Which is reflected in a bunch of the responses to the reveal of this new game, where people are mentioning they have never played a Divinity game at all.
