WWE has a habit of screwing over Matt Hardy, treating him like he's only useful when he's with Jeff. He did well with ECW brand before he left for TNA again. I enjoyed his Matt Hardy V2 character, which I almost feel is a predecessor to the Broken Hardy persona. And as far as I recall, he, historically, hasn't been great on the mic, but he does absolutely well in the ring. WWE has a habit of screwing any good character just to put over someone like Reigns or John Cena.
Well we just gotta make sure that Matt stays away from Reigns, maybe hovering more around the top of the mid card, and he'll be okay lol I don't need him battling Lesnar for the Universal belt or anything (Though I imagine him and Heyman could have some pretty interesting promos). But the potential for Balor, Wyatt, down the road with The New Day, The Miz, for those with good characters or ideas about them that could make for good interactions, because Matt is a fine wrestler, nothing amazing these days, but consistent that I've seen with him returning, it's the absurdity that I understand about "Woken" Matt which will make things fun.
Because honestly, it doesn't really feel like there are a lot of good "characters" in WWE these days. There's a couple for sure, but like proper characters on the level of Wyatt or now Matt, there's only a couple really good ones.
