Respawn painted themselves into a corner with Axle

I think the biggest issue people have with the character is that Axle's abilities completely violate the flow and timing of fights. Even at their strongest, characters like Octane, Horizon, Ash, and Alter still remained within the bounds of the game's timing. Axle has completely changed that timing, and for a lot of people it ruins the experience and flow of the game.

Axle will invariably get nerfed, but how will that look? The way the kit is designed pretty much makes this character all or nothing.

The tactical ability: This is basically an Octane ult on steroids that refreshes way too quickly. Players stay low to the ground, can potentially get double jumps from the purple perk, and the pads remain forever (unless destroyed, similar to Octane's pad).
Possible nerfs: Substantially increased cooldown time, only x amount of pads deployed at one time, substantially decreased sliding distance, pads disappearing after x amount of time, only Axle being able to use them.

The ultimate: heat seeking missile that goes through any fortification
Possible nerfs: Gibby bubble, Newcastle wall, Wattson pylon (stops ult entirely)/fences, Crypto emp all make the ult detonate before breaching.

All of these nerfs will greatly diminish the potency and viability of this character. From what I've seen, and short of a substantial re-work of the tactical and ultimate abilities, Axle will either be OP or nerfed so badly that no one will want to play the character.
