OCTAINE'S ABILITIES
If the leaks are correct, then it's good that we have a chance to see the abilities! This one was also posted on Reddit, you can find the source here.
Passive Skill: Swift Mend
Health regeneration out of combat
I've seen many people discuss how powerful these abilities would be, but I tend to disagree with them. While I think it can be useful, it's unlikely that this skill will heal you fast enough to make a huge difference. Yes, it can give you some health back to survive the fight, but you'll probably take too long to recover for it to really have an effect. This will probably come in handy when you're low on meds and have just won a fight, but it won't give you a huge head start over other players.
Tactical Skill: Adrenaline Junkie
Adrenaline, after injection of which the character moves 30% faster for 8 seconds. Activation "costs" a tenth of health;
I love the idea of this ability and the fact that it has a real cost when using it. It also pairs nicely with a passive, so you can use it to travel and regenerate lost health. This will make Octane a more aggressive legend and give you plenty of chance to flank without having to worry about slowing down.
Ultimate Ability: Launch Pad
A portable launch pad that allows you to take your allies into the air and plan
This can be a pretty good ability, but with the amount of mobility already in the game, I'm not sure how valuable it will prove to be. You can already relocate with balloons and there are ziplines everywhere. I would compare it to Pathfinder's ult, but obviously I think it's better because you won't be as much of a target when you're flying through the air as if you were using a zipline.
