The point is, BG3 SHOULD be a serious RPG. Why? Because it's the third installment in an entire string of serious RPGs.
You are comparing story to mechanics. I agree that the immortal child missile bug should be patched, but if you want to equate mechanics with storytelling, original BG1/2 are worse. How is killing handled in those games? Your alignment won't budge no matter the amount of killing innocents you commit. Instead you get a drop in "reputation", same reputation that can be easily brought up by donating at temples. So you can be a lawful good mass murderer widely celebrated as hero. Does this sound serious to you? And it's not even a bug, it's intended by the devs. The funniest part is even your Bhaalspawn powers are dependent on how good your PR reputation is.
