Most arguments how terrible Wits is are based on the thought that you can prepare. Pull enemies, cast Clear Mind, knowing what is where. Of course I know any enemy in Act 1, where he is and what will happen. But the first fights were always the best, even with a loss (Radeka). And going first because of Wits was the best what could happen in an ambush. So I will keep my opinion that Wits is an important stat.
Those racials will however not influence my choice of companions. I like Lhose, Ifan (although his beard annoys me) and Sebille and they will be it whatever they have or have not.
