Just so you understand THIS is the reason that FJ is as strong as it is
Now OK I get it can be argued that One Man Army is the problem here but scavenger effectively gives you unlimited explosives too and at the beginning of MW2's life when people didn't know about OMA they did use scavenger for the same results.
The only way I'd see FJ being removed or nerfed (it already is from BO1) is if explosives gave you a choice of the types of explosives and none of them are resupplied, like in COD4 (3 frags OR 2 C4s OR 2 RPGs OR 2 claymores). At least then if people spam their explosives recklessly getting no kills, then it's tough luck on them.
It doesnt need to be removed. Nor did I even suggest nerfs. But I understand why its there. Half the time when I use fj I just put on engineering and I think to myself how uselss fj is now. I carry one emp with engineering and i hardly get killed by claymore/bouncing betty
But if you ask me bouncing betty needs some tweaks. Crouching when it goes off has to be the biggest flaw iv ever seen in explosives in this game. The only thing its good for is to make sure nobody gets past a certain distance, even then a friend or sensor grenade will do the trick anyhow.
Yeah, make the bouncing betty faster to rise and then explode the shrapnel lower down so then you'd have to be prone to dodge it. I couldn't understand the complaints about players insisting that there needed to be more of a delay to help dodge it. That's just stupid. Can we have Juggernaut back then? The developers have put enough tools in the game to deal with bouncing betties but some people refuse to alter their setups and just whinge to force nerfs.
OP you are actually wrong.
I use Flak Jacket. And I have been killed by every explosive in the game while using it, without being injured prior to the explosion.
If you stick the flack jacket user with symtex they are dead
If you blow up the RCXD right at their feet. They are dead
If you direct impact them with a SMAW or RPG they are dead
If you land a frag right at their feet they are dead
If you blow up a C4 right at their feet or direct impact them and blow it up at the same time they are dead
I also believe I have only survived twice to hunter killers
I have also died to bouncing beaties while wearing flak jacket.
Edit: I guess there is one explosive that has not killed me: The only explosive in the game that hasn't killed me while having flak jacket is claymores.
