They should modify martyrdom so that you only can drop a grenade when you die if you actually still had a frag grenade left. If you already used it, then you don't have one to drop....
As far as perks such as nerve gas that kills everyone except your team on a whole level, or perks that allow you to have noobtube, RDS, and silencer all at once

, uhhh, yeah... Why don't we just have an uber perk that takes slot 1, 2 and 3. We'll call it the GOD perk, where you have infinite health and ammo
Maybe we can get a perk that just makes it so you win the game

I mean, c'mon... Perks that make it so you are impervious to head shots, nades, martyrdom, claymores, etc.... What's the point of having those things then?
At least with bomb-squad, you see the claymore, so you either don't go into the protected area, or risk getting shot at while you try to shoot the thing, etc, which the guy who set it, can than hear, and you can have a fight... With a perk that makes it so you run right past a claymore without setting it off... That defeats the point of having a claymore then.
Stopping power and juggernaut cancel each othre out, but you still have to fight to kill the other person. The better (or luckier) person will win....
A perk allowing you to be impervious to claymores, nades, etc, is like having a perk that makes it so whenever you encounter an enemy they have no ammo, so you can go in and knife them without them realizing they have no ammo.
And making last-stand so they are considered friendlies to everyone except the person that put them in last stand?

So I guess if I go into last stand, I can go to town and kill your whole team since they can't damage me, all so you can get your +5 or +10 after several seconds....
If you make it so that if you die before you shoot the last-stander, and you want them to die right away so nobody steals your kill.... Then there is no point in having last stand in the first place.
