I trust the developer has their legitimate reason to cut her off.
I don't. What sparks that degree of trust and confidence in you, all evidence to the contrary?
Larian have frequently shown their willingness to misinterpret data or extrapolate feedback into the shape they
Want it to make, without any insightfullness, and use it to jump to the conclusions that they most want to draw, even when those conclusions are completely unsupported. We saw this time and time again during their data feedback during the EA, and it never improved.
But I will say that if you don't see how a companion of a race we don't have represented, and a class we don't have represented, would be a better choice to run with over one who is another Elf (in our party of several elves and halfelves), and another Druid (in our party with an established figure druid already available), then I don't feel as though you are really thinking very hard. Assuming nothing else about the character than what we specifically know was planned, that alone is a big motive for her inclusion.
To reiterate to others about focus here (and because there's enough about the Halsin travesty already), this is mostly focused on the
inclusion of this character that we missed out on, not necessarily about her replacing or over-writing a different one we did get.
