I agree with ninja. I picked deep gnome for my first playthrough (directly went for tactician) and I was quite disappointed that my superiour darkvision almost never mattered. I had Lae'zel in the party the whole time and in the entire game there were maybe three fights where not having darkvision gave her a disadvantage.

In my opinion, given the powerful items and the fact that we can long rest as often as we want, race is mostly a cosmetic choice.
