I think there is space for a new tank in overwatch.
One with a flamethrower who looks something between a rein and a zarya.
Uses primary and secondary fire like zarya but with fire. E could be a blocking wall of fire blocking damage but walkthrough for allies, burning enemies.
Shift could be a dash, a bit like reins charge but short distance.
Ult could be like “scorch the earth” that works similar to hammonds mine field. Like the hero targets the ground and pulls the trigger that sends it up in the air a bit and the enemies outwards a bit and leaving the ground burning for a period of time which also keeps burning enemies like Ash dynamite.
