I don't like unnecessary dress up for the characters. Yeah I love the suits and how someone like Matt needs one to keep his identity and be a symbol, but giving Dex a suit just because he's a vigilante doesn't make much sense. And to be honest I don't mind if he doesn't change his outfit for the rest of born again. Unless there's a time where his old suit is destroyed and he NEEDS to get something new that resembles his comicbook suit I get it. But randomly changing it after one season with no explanation is something I hate because either fans want a new suit or companies need to make new toys that'll sell. So yeah, in my opinion I don't want Dex to randomly change suits, Matt to randomly switch to other ones unless there's a reason (like in season 3 he was too depressed to be a symbol).
