Add -ACC and/or -ToHit to Superspeed

And you want those debuffs for the person using Superspeed as well, correct? After all, someone running around that fast would have a much harder time aiming and ensuring a shot hit...

No?

Perceived theme isn't grounds enough by itself for changing a power, imho.

Not according to superhero comics. Superspeedsters have no problem hitting, but have a hard time being hit.

That said, I don't see this suggestion happening. If you want it, my suggestion is to build for positional defenses.

True, but according to the comics Superspeedsters don't have to worry about relativity unless the plot calls for it - which probably explains why everyone the Flash ever knew wasn't dead by the end of his first issue - so I'm not sure they can always be trusted

This is a game that the devs put balance in place for playability across many ATs and combinations of powersets, let alone IOs, incarnates, etc. Comics have writers/artists that can change the "super speeder" to fit the needs of the story from issue to issue.

And the people in comics are completely invulnerable one issue, but brought down by a papercut or a green rock the next.

So by that argument, every time you activate a power, there should be a random buff or debuff applied to you (with a .001% chance of instant death.) OK, maybe not each activation, but each mission, arc, or day.

"Sorry, guys, I'm at a -5000% ACC penalty today for some reason, I think someone sneezed at my picture."
"Oops, seem to have developed a moral aversion to hitting women. Cant' help on any Arachnos, Malta, Knives, Carnie or Freakshow missions today."
"Dang, I looked west at 3 PM, I'm now weak to energy damage."

Wait.. you mean you can't run faster than the speed of light and travel in time by running *in place* on a treadmill?
