I've generally observed 3 camps here in terms of opinion - people who want BG3 to be more like DOS, more like 5e RAW, or more like BG1/2 - and on any given day or thread, any of these groups could be the most focal.
Compared to the Steam forums, I can't say that this place is toxic. There is a small, vocal minority who are very emotionally invested in what they want BG3 fundamentally to be. Given that, sometimes discussions have devolved into emotional venting instead of actual feedback and game discussion.
Ehh. Not great breakdown of the three camps you've identified the last two largely overlap (if they were distinct camps I would reside in both) and the first camp "people who want BG3 to be more like DOS" has perhaps 3 or 4 members. There as many people calling for the return of the 3.5 ruleset as there are advocates of cooldowns and action points.
