Just to be a lore nerd, wood and wild elves definitely *can* be monogamous, even if their overall culture tends not to be. For example, Kivan in BG1 is extremely dedicated to his (unfortunately dead) wife, and he's a wild elf.

Anyway, from what I've seen in clips of Halsin's epilogue dialogue, it seems like they took some of the feedback into account, which is nice to see.
