Or is it just me?
Grenades are less effective now than they were back in Reach. Lessons learned.
I quite like them in this game, they were far too powerful in Reach.

I have to agree, I hardly get any grenade kills now. They just don’t seem to work
They seem fine to me. I get plenty of grenade kills. Now players who spam grenades can no longer get cheap kills but when I accurately throw one I get rewarded with the kill.
It’s you
Why is the pulse grenade in existence?
I got an Overkill on Abandon KOTH with frags recently. (90 points instantly IIRC) 
But yeah, they’re no near as powerful as in Reach.
They have been weakened so could add the “explosive” upgrade, same way that you start with less ammo now, this was so 343 could add the ammo upgrade. They took things away from us so it looks like there giving us more options, but they really made us weaker.
