I know it's kinda late to complain about this but
the Groundbreaker gear is really ugly, and honestly looks like garbage even as a costume. It also has absolutely no practical use. It's really not a fitting reward for people who helped test the game.
If not that, then at least the medal should be wearable so that I can have some way to prove I played in the beta without putting on that ugly helm or armor. Maybe it could add an effect to the player's name or something? Maybe "BETA" above the name or below the guild? I don't know.
You did nothing special to deserve anything at all; getting a unique armor set for doing nothing at all is more than you deserve as it is. Gift horse in the mouth, etc.
Moreover, style is subjective. I know several people that like the armor's appearance.
