That's assuming you aren't using him for anything else, which you should be... With fast that gives him up to 15" a turn, more than enough to get anywhere on the board by Turn 3.
Also, with Misery you're getting min 4 out of his melee attack if they take the Burning damage.
He's small and has multiple defensive tech things giving him some survivability as well.
And if the opponent drops 2 scheme-marker schemes from their available pool because of one model of mine, I consider that a win as well. Not saying he works into every pool, but I definitely took him in GG0 if there was the corner-scheme marker based one and prevented a good number of points.
