I’ve used the in game suggestion interface to suggest adding cosmetic ensembles of all the white gear sets sold by vendors in the starting areas as rewards one can buy from the Trial of Style. Perhaps if more people suggest it Blizzard may take notice.
I specifically ask it to be cosmetic because there is no plate at those levels on those vendors and it would be kind of unfair to leave plate wearers out. There’s also the fact that it would give a few options to other armor types that they otherwise would not be able to use, several of which look like they could be an armor type different from the one they actually are.
