Which Legend for 1st unlock?

Hi @Psycho4Real 

Octane - Small with simple abilities which boost his speed and make him jump and a passive ability that heals him over time. He is good fun to play but probably has less gameplay depth than say Caustic. Choose Octane if you want fast, furious and fun gameplay.

Mirage - Not quite as small as Octane, each of his three abilities use decoys to bamboozle opponents, plus, his passive and Ultimate abilities also cloak him for a limited time - although he is not completely invisible to opponents while cloaked. Choose Mirage if you want a slight tactical advantage in combat.

Caustic - The largest of the three and most difficult to play. His size is probably due to the fact that he is the only one of the three here who has abilities which do damage and also hinder the movement and ability to see of players affected by them. His larger hit boxes are not to every player's taste, but played properly he is very strong. But he takes practise to get the most out of. Choose Caustic if you want close range combat around his gas traps.

Good luck with your choice.
