Basically, you can activate 10 grenades in a row, and no turn will pass (or 10 mininukes, or 10 goo canisters. Whatever, haven’t check all objects, though). It’s odd for me.
That’s all. Quite a short request. Maybe, it’ll be hard to implement, don’t know.
Well, theoretically, if you were wearing a snazzy grenade harness, then activation would be as simple as pulling it off the harness, leaving the pin behind and activating it. 
We shouldn’t forget that Hollywood made us believe that the pin is easilly pulled from the grenade 
. Otherwise grenades would blow up inside our rucksacks . It requires a bit of time and strength .
Even in FPS video games where you’re sometimes killed even before you activate your grenade
Waddaya mean? They’re “Cooking” it xD essentially activating it waiting for the timer to go down (Wouldnt really be needed in real life, seeing shrapnel would fuck you up)
I mean, even in FPS games or Hollywood movies you need time to pull the grenade’s pin . Assuming that you have your grenade in your hand already oO .
But who “wields” grenades in Cataclysm ? You need time to take the grenade and to trigger it.
So… Imagine this. You take one grenade, activate it, put it back in your pocket/backpack, take another one, put it also back in your pocket. And no time passes while you do this. This is what Cataclysm is like .
p.s. BTW, the grenade’s pin is not the only thing you have to pull out. There are some blocking mechanisms also. As I said, otherwise, grenades would blow up in our rucksacks. Or millitarys rucksacks oO .
I thought you pull the pin, and hold the pressure thing (I forgot what they call it) and when you let that go, a thing pops out shrugs I dont know too much about hand grenades. But yeah. With a grenade belt it would be easier.
Also, if you drop a grenade on the ground (Inactive) and threw another one at it (active) would they both blow up? (In cataclysm)
Spoon ? Hold the spoon. Also, some grenades have some sort of blocking … safety clip (scheme1,example2).
wiki example
But anyway you can’t hold the spoon on two greandes at a time. You can’t even pull the ring from the second grenade, while you’r holding the first one. Cause pulling the ring requires some effort and strength.
Maybe, with a grenade pelt it would require less time to activate, but …that’s a whole different feature oO.
This feature is not about grenades . Every item activation costs time. Even dropping items from your inventory costs some time.
It would make a certain amount of sense. +1.
