We started Act 2 dressed like mercenaries, we stood at the final boss dressed like the Clown Fiesta Crew. I'm a huge supporter of colour customization ala BG2, the circles (and especially outlines) being customisable would help a lot, as when everything is covered in necro fire and corpses knowing which one of the metal scarecrow is your current character takes a while.
Ideally without dye but, hey, I guess that's a thing that'll be added in later patches. Seems sort of obvious.
As an aside my playmate is the happiest he's ever been in our current playthrough, because he got the hat he wanted for Beast, which he didn't get for the Red Prince in the previous game; as it was a finesse helmet. Customisable gear is where it's at.
