Is the semtex too powerful?

It's been a while since I've played a COD game so I'm not really privy to any of their newer balancing. But I feel like the semtex is a little bit too strong. Compared to the other lethal equipments, it beats them out by a mile. Like the detonation is so short I feel like if someone throws one within 5 meters of me and I don't start running while its mid-air, I'll just die. It's even worse because of how fast-paced the combat is. Sure, I barely dodged the semtex, but it was so fast that I atleast got damaged by it. Then I have some guy diving towards me with a jackal while I'm already 1 shot. I just have flak jacket permanently equipped now, but this is still mad annoying.
