Just to post the current Karlach Discord posts, older ones that had even more upvotes have sadly passed on to the realm of non-existence. Those, along with hug option, Minthara and Halsin fixes, polyamory reworking and epilogues are the most upvoted and so on a regular. It'd be really out of the blue for Larian to give time to every other feedback/wish but not the biggest ones.
