Sadly, this sounds as if the Ambush problems haven't been addressed.
I don't have a problem with Ambushes being open to cheese. I'm not even sure what cheesing an Ambush means, and I don't care if other players can pull that cheese easily. My issue is that I cannot successfully perform an Ambush in the first place.
I'm a little puzzled by this as I'm not sure how I personally would cheese the system if it now works reliably as it did when I tried to test it. Sure, I could use it to get each of my party to complete an attack at the top of the first round, rather than having to wait for their place in the initiative order, but that sounds a reasonably fair reward for a successful ambush to me, and would have no benefit beyond that first round. What am I missing?
(As an aside, I'd suggest that more detailed discussions of what a good-aligned playthrough is and whether BG3 allows one should be taken elsewhere. It's a perfectly fine topic to debate, but as I think I said earlier in this thread, I'd like to keep it for the Q&A on the creator day. Short exchanges to clarify or comment on answers are fine, but if if starts getting longer than that let's take it to another thread.)
