Playing TFs just now with lots of Kinetics switching between various mission map types, and seeing the different new power suppression options it occurs to me..
Null can shut off (external?) Speed buffs, but you must visit Pocket D each time as far as I know, which is not practical when you may want them in a big outdoor map and then not have them in a small cave map.. thinking LGTF for instance.
So what about turning that idea into a power, or set of powers, to determine your maximum speed? Sort of the reverse of Afterburner.
I feel given we're superheroes (or villains) after all, we would have the ability to adjust for things like an increase in speed, Walking instead of running, without losing our powers essentially. Even a user of Super Speed wouldn't be in an all or nothing situation in every case.
