Gotta remember trailers can often be deceptive and will often overly highlight elements for marketing reasons..
They went hard on the "misfit team" element because misfit team movies sell. The tone is also a lot like what you'd find and any given table, the face bard who tries to make plans, the paladin trying to go for those glorious kills, the to the point but generally chill barb. I bet the studio is hoping for grass roots advertisement from a lot of fans excited to see their table on the sliver screen.
