Okay, this is a bit too much for me to ignore. I assume you are referring to this thread on the Solasta forums.
https://forums.solasta-game.com/forum/baldurs-gate-3?page=3The majority of the posts in that thread are from before BG3 EA even started. And the very last post in that thread was from
5 months ago.
A lot happened in 5 months. For instance, an entire patch happened. Community feedback has taken a sharp turn towards the systems needing an overhaul. And honestly, Solasta had little to do with that beyond how reactions are implemented. We've always had people arguing height advantage and backstabs were dumb before Solasta ever came into the equation (the megathread about height/backstab on these forums was started the same week that Solasta entered EA, but a quick skim of the thread actually yields absolutely no mentions of Solasta in there at all), and Tuco's 'toilet chain control system' crusade had nothing to do with Solasta specifically either (it's a lot more 'every other cRPG in existence').
The only thing Solasta really did was amplify the severity of these issues by providing a direct reference point that flies in the face of Larian's PR trying to convince everyone that they thought that the base rules wouldn't make for a compelling combat system, when it appears most are now in agreement that the changes they've made ended up having very bad long-term effects on the overall balance. I suspect half the people that posted in the height/backstab thread have yet to play Solasta and likely never will for a good number of reasons that no one should begrudge them for, nor did a good chunk of people in that recent poll from a couple weeks back that voted against the current combat design. And they came to the same conclusion anyway, for slightly different reasons.
The Solasta discord is generally lukewarm about any kind of comparison, but people generally don't talk about such things there because it turns out the BG3 subreddit has become a far better venue for doing so in recent times, now that people are no longer getting downvoted into censored territory for posting anything remotely considered negative anymore. Also, thanks to that thread, I just remembered that BG3 was originally going to have group initiative. That would have been a pretty big mess. Glad that was reversed before EA began, or else there would have probably been a lot of complaints about entire parties getting nuked before the player got a turn, and stealth cheese would have been outright mandatory.
(BG3 dialogue options were originally going to be done in vague third person speak too. That was also not very popular, and it's a good thing that also got changed before EA launched. Though I wonder how much of the script had to be redone because of that.)
Although, thanks for giving me an excuse to check all this. A quick stroll into the off-topic section of the Solasta discord yielded information about someone trying to remake all of BG2 within the engine of Neverwinter Nights. As I haven't played either game but have heard how NWN's engine is apparently legendary among programmers in general, I am curious to see how this turns out. (And for the curious, no one seems to be talking about BG3 there either, but there's a fair amount of people from a month ago that seem to be bewildered about the new Dark Alliance, ha.)
