I can see that there many different opinions about the way BG3 should evolve and improve. A half of the people is here because they love BG1/BG2, other half because they love DOS2.
The problem is that these games are completely different... Honestly I think that the only way to please everyone will be to introduce same system like in Pillars 2 or Kingmaker - RTwP (more BG1/BG2 friendly with all D&D 5e rules) and TB (more DOS2 friendly with bit more limited 5e rules).
I know it could be quite difficult and time taking as this will require to re-shape BG3 a lot, but who knows - maybe this could be the way ?
