I wonder if Wyll being chill is a question of personal perception or party combination. I can't have Wyll in my party for long because he seems so eager to offend everyone and has nothing substantial to say, while I find Gale and Lae'zel to be really wholesome together because they have nice, interesting conversations with each other.
I think Lae'zel's banter with everyone is among the best. Wyll doesn't know how to talk to people.
Which reminds me. There's banter between him, Astarion, and Gale during which we find out that he doesn't know who Cazador is, while Gale does. Wyll really should know though, he's the grand duke's son and Cazador owns a whole ass palace in the city.
