Hoo boy...
Let's think about it this way, then.
Let's say he *does* get this buff. It assists a *little* in allowing him to catch up to his team. Problem solved, right?
False.
He'll end up being the fastest legend, and just might have to wait for his teammates to catch up.
It just might be abused the hell out of by taking advantage of a faster movement speed during combat. It'll be easier for him to slip away, he'll be harder to hit because he's moving too fast for people to compensate during crisis situations. (Don't tell people to just aim better, someone is going to fall up short in aiming, and it ain't your place to say.)
Why use Octane if Crypto has a passive movement speed buff, bottom line, without needing to be shot at, nor consuming your HP bar. just a basic speed boost for no reason other than the specific purpose to catch up to people.
You see what I'm getting at?
The movement speed buff, sure, would do wonders in allowing him to catch up to people, but that's a BASIC BUFF for a specific reason. So no. Step down from that throne, and instead, think of a way to make his drone more useful.
It doesn't matter if it does something instantaneously, those are situations that do not inhibit your enemy, only granting *minor benefits* to your team. He's one of the more worse legends, and desperately needs a buff in a different field.
Hope this got through to you, @zombieshoota5000
