Octane buff that will make him S tier

Octane is my favorite legend, and will always be because I just love his speed gameplay. But he's supposed to be the fastest legend but other legend abilities simply do better. This buff will make him unique and even playable in the big leagues. Please feel free to leave comments if anything seems too op.

1. His passive. I got basically two ideas for his passive. 

Swift mend: Octane constantly regens health overtime (even when taking damage/using stim)

Or

Swift mend: Octane restores health overtime (but the speed is buffed to 1:1 instead of 1:2)

Personally I like the 2nd one better since I do think it's kinda too slow, especially when you wanna keep using your tactical. 

2. His tactical. This is the main change that needs to happen since most characters beat his tatical, and here is my idea.

Stim: Move 40% faster (or a speed that guarantees he goes faster than everyone) for 6 seconds. Cost health to use. Cannot be slowed (absolutely can not be slowed during stim, but it's balanced since he still needs to use health to use his tactical. Meaning Watson's traps, grenades, caustic's traps, etc do not slow him when he is on stim, this should also allow him to run while strafing so he's hard to hit while stimmed)

3. His ultimate needs to be more unique. Currently Wraith's portal and pathfinder's Zipline completely beats octane's jump pad. So here's how it'll be as useful. Not to say it's useless it just needs to be reworked. 

Launch Pad: Deploy a Launch Pad that catapults users in the air (his jump pad can make them go very high with buff). Press the jump button again to activate a double jump to the direction you are going making you go higher and farther. (This way, you don't have to be an easy target in the air and go on high buildings along with your team. It now can compete with Wraith's and Pathfinder's ult, or be used aggressively and flank enemies or even defensively along with good transportation).

Secondary passive idea (like fortified and low profile).

This is not my idea but here's 3 options.

Speed Demon: No reduction to movement speed while holding a weapon 

Speed Demon: Able to shoot while running.

Or

Speed Demon: Able to shoot while running and no reduction to speed while holding a weapon 

Personally I think the 3rd option is a little too op but I rather have the first option. But this change would definitely make octane an S tier legend.
