IMO Good gameplay w/ bad story can work. Good story w/ bad gameplay can't. With BG1&2 you got both which is what made it great. I think BG3 is decent gameplay and good story. The decent wil be improved. That said, I am dumbfounded that no one chimed in with a different experience at the grove. I got pissed and killed Kaga? Karga? too, but my experience was VASTLY different and things changed DRAMATICALLY.
Nettie joined in the fight against me. When I left the grove the tieflings had slaughtered all the druids. Wyll died even though he was in camp. When I later tried to free Haslan, he had escaped. After killing the goblin bosses, Haslan understood why I killed the druids and said it was his fault and that he shouldnt have left.
