Trivia

 * In general, Legends come in one of three sizes (small, medium, large). compensates for having a large hitbox.  countered the advantages of a small hitbox. Daniel Z Klein described them as "chewing gum and duct tape holding the game together." In, Low Profile was removed as the team felt confident they could balance small Legends without it.
 * Pathfinder had Low Profile despite not having a small hitbox because he was very thin (at the time) and had a lot of mobility. Revenant accidentally shipped with Low Profile despite not having a small hitbox because he had Pathfinder's skinny (at the time) hitbox earlier in development.
 * The class perk is Pathfinder's original passive.
 * Class perks for the other three Legend classes—,, and —have been datamined, but only the Recon Legend Icon.svg Recon perk was added. On Reddit, game designer Daniel Zenon Klein offered some insight on to why.
 * The leaked Offense perk allowed Offensive Legends to have two extra slots for grenades. Klein revealed that the devs had also considered allowing Offensive Legends to stack grenades to 2 again. Klein does not think they will move forward with this perk because he believes the game is healthier with less grenade spam.
 * This perk was eventually added in the form of Fuse's Passive ability,.
 * The leaked Defense perk allowed Defensive Legends to give shields to revived squadmates. Klein said that he does not want to take the Guardian Angel perk away from the gold backpack. The devs also considered having Defensive Legends being able to fortify doors, making it so that only they can break them and it takes extra kicks for them to break; this perk was found to be too situational.
 * The leaked Support perk allowed Support Legends to find extra supplies in blue supply bins. This perk actually already exists and is on Lifeline. Klein says they originally intended for it to be on all Support Legends but they ultimately decided to put it on Lifeline only. However, Klein stated they might revisit this perk.
