Is it really like 30 seconds or more per grenade?

I was using up some old C22's I pulled from a crate (crafted pre-cu, pulled post-cu) and could only use one every 30 seconds, maybe even slower. I didn't mind doing next to no damage, but it would have been nice if the reuse timer was a little slower because grenades tend to draw a lot of agro and thus more targets needing grenading.
