I was thinking more in terms of "how can a PC counter enemy speedster", or vice-versa, than how a GM could fuck with them.
>It would also come off as the GM not coming up with ways to challenge the speedster and their powers and instead resort to cheap tricks.
Nobody promised you'd be fighting on a tarmac. That said, GM shouldn't even NEED to do anything like that — the collateral damage to surrounding buildings from the fighting would complicate things all on it's own.
If you don't want that, tell the other guys to exercise a little restraint and not level the whole block fighting the bad guys.
This is mostly preventable and is usually the direct consequence of players' own actions.
Otherwise what >>95930418 guy said. And good catch with the area-based attacks, forgot about that.
