As I said in another thread:
I doubt Larian looks at feedback and implement changes that are "popular on the forums".
A good designer analyses what the issues people have, and looks at changes they think would be good within their vision of the game.
Things like "Realtime with pause" is a vocal minority issue, and I doubt Larian will look at that and go "yeah let's totally change our vision for this game". I think they can look at it and see WHY people think RTWP is "needed".
One thing that comes up a lot is "Turnbased combat is too slow" or "not fun to just press attack each turn"
These are mechanical issues that can be fixed in more ways than one.
Other feedback such as "Don't make all the movement abilities into bonus actions" stems from other things. Some of us feel it strays too much from DnD5e, and diminishes the Rogue class significantly. I also feel it takes tactics away from the game.
Things like "surfaces" and "barrelmancy" can be tweaked, and don't need to be removed from the game. To me the issue isn't surfaces, but the imbalance something so huge adds to the pretty tightly balanced DnD5e combat ruleset.
A Survey is a good idea though, and honestly I'd love to see EA be a testing ground. Would be nice with a change being implemented, and people be allowed to vote on "was this more or less fun" sort of thing.
I have faith in Larian though, they seem to know what they are doing with EA
Here's a funny one for you: My experience with Larian didn't start until well after the hype for BG 3 was rolling, although still well before EA was announced. In that time, I got DOS 2. There were two reasons for that:
1. I have always hated TB combat in video games, to the point where I just really didn't play them, and my first taste was ToEE. So I got DOS 2 because I wanted to get a handle on how they handled the combat. I'm neither for, nor against adding RTWP, even though I actually do prefer it.
2. I wanted to see what Larian was about as far as world building/gameplay outside of just combat.
After playing, I decided that I was curious enough to come in to EA, knowing full well what I was getting myself into. I've used the Crash Report when I had a crash, and I've left lots of feedback here. At this time, all of my posts on these forums are in this game's sub forums. I got the game through GoG because I hate Steam, even though I have a Steam account.
Their process for dealing with feedback was laid out in one of the articles attached to the launcher, and I actually read all of them. They read it, take it to committee, and do what needs to be done from that, and I like that approach. It takes all the positions provided, and weighs them against what their design goals are, and, more importantly, what WotC will approve, because, at the end of the day, despite all the "it's not D&D" posts, everything was approved by WotC, and they, more than anyone else, get to define what is, or isn't D&D. I may not agree with everything they do, but they own it, and they are free to do whatever they like with it.
