I can’t say I don’t blame him. They never knew what to do with him ever. On flash he always had to play second fiddle to Barry always getting knocked out. You also can’t fully utilize him on legends or every problem gets solved immediately. It was painfully obvious they had no idea what to do with Wally. He’s a character they could never really get right and I’m sure he felt that so he’s probably off to pursue projects where he as an actor can be better utilized for his talents. Wish him the best of luck.
This past season of flash I would have almost spent the first half of the season with Wally on team flash as flash while they showed Barry in the speed force with some sort of story so he got screen time as well, it would have solved the underused Wally problem and shortened the horrible bloated devoe arc.
