#1: Finn Balor

What's common between Sami Zayn, Finn Balor and Samoa Joe? They are former NXT Champions who found it really tough to succeed on the main roster. Finn Balor won the Universal Championship in his very first PPV match, defeated Roman Reigns on the very first night, and has repeatedly featured in the upper card of WWE.
However, WWE has never figured out the formula for Balor. Placing Balor in feuds with the likes of Baron Corbin, Lashley, etc. has killed any momentum he ever had. Balor used to be an ultra aggressive heel in NJPW, and an intense babyface in NXT. He has none of that on the main roster.
The "happy to be here" and "ever-smiling" babyface gimmick never worked for any superstar in the history of WWE.
A switch to AEW where he can reunite with his former Bullet Club mates will be a much welcome move.
