This mechanic was there ever since the first days of the game… Yep, this is originating from the alpha version where it was added.
I don´t see why is OP mad about it, just kill the bastard and run, or just run because as it is the last effort measure, it is guaranteed suicide. Either way, you get a kill…
All you need to do is not be an absolute donkey and use your brain. That is literally all it takes.
expecting too much already
sorry but i will see You in reality when You Use a Medikit and @The Same Time use youre Grenade
Dunno what game you’ve ben playing, but it was added on 8 September -
Also, you may now drop a cooked grenade under yourself while downed using the grenade selection button. Thus either avenging yourself or masking your retreat to safety with smoke.
Dunno if you ever noticed that you could drop your grenade / explosive before 8th September, I’ve been doing that for at least 3 months now (occasionally). Now what they introduced is ability to actually “cook them”, which I don’t use anyway, I just do it my old way, just drop it when I’m down and know I won’t be able to use medkit in time.
Yeah, they can drop the grenade, but they can’t cook it so you have 5 seconds to do your dance then GTFO.
dude u even know what spam is? every post u have made in this other than the most recent has been spam and i have flagged every one as inappropriate or spam. also get over urself and ur addiction to acting like America is the wholly pathetic source of all ur problems. have u noticed the only word u havent capitalized in ur posts is America? if ur so butthurt just cry me a river and realize its a legit tactic in the real world
I bet he doesn’t even know where America is on the map, and the fact it’s not a country but a whole continent spanning the two hemispheres… 
Using both grenade and medkit doesn´t really make sense because you are going to die either way unless you have a perk on faster healing (which beats the point of using a suicide grenade in the first place). Sure, it might be possible, but why the hell would you run towards the enemy with a knife if you have any ammo left?
Also, I don´t see how it is not understandable if somebody tries to save himself first and when everything is lost drops a suicide grenade.
Again, in all possible situations it is easy to evade this move, all you need to do is
If you want to flex over somebody by taking a knife and running towards the downed enemy and wait there to “enjoy the moment and let the grenade explode” instead of finishing him with a bullet, that is your flaw in play.
