Voyager stole the hell out of everything.
You make it seem like DS9 was original with the Jem'Hadar.
Anyways, the Hirogen had armor strong enough to let them walk on Suns. I think they take the Jem'Hadar.
And given how constrained the show's premise was, there wasn't anything they could do with their enemies that WOULDN'T make them monsters of the week or add to the show in a meaningful way. So there's no point in complaining over that. It's pretty much impossible to tell an epic story with a plot like Voyager.
when do they say they can walk on suns?
In "Prey" one of them mentioned he hunted something while walking on a collapsed star.
