Octane is the only good legend
i could not dissagre even more
Who is good then
literally any other legend like Gibby, wraith and pathfinder, Gibby useful for team, Wraith really good for allowing rotations, and pathfinder to find next zones and he has a good movement possibility
Octane is normally used as a trick shot character as he can use his launch pad do so. His launch pad may also be used to allow not just standing teammates but also downed teammates to get out of the storm. And obviously it makes it easier to reach hard to get places in which you can hide and destroy the launch pad so no one can get to you.
