Not worthless throw and wait for the flash then run/strafe-jump take out the targets. I use it on my MP5 class (i usually dominate with it)

Flash will hurt you the most- Don't know hwere your going, can't see people, people shooting at you. Not good...

Well it's a personnel opinion i hate them and prefer the concussion due to the range and effects but you also have to think about it from someone else's standard's and see why they like it maybe cause of it's quick damage and fast kill factor?

I would say this:

Flashbangs for head to head combat

Stuns for enemies that are running away from you :P

flashbangs worthless?? i don't use it but I ALWAYS get killed cause i was flash! worthless, I think not

How are flashbangs worthless? I'd like what you're smoking. They're one of the most frustrating and cheap things in this game.

The flash effect last longer than in previous COD games and people spam them like no tomorrow thanks to Quickdraw pro. They have virtually no counter either since Blast Sheild Pro's effect does absolutely jack ****.

They should just get rid of flash bangs/concussions all together. What ever happened to the days of FPS games where you earned your kills instead of mindlessly spamming cheap ass tactical grenades at people to get an easy kill?

I find the concussion ones better than the flash...which I never use.  They're similar but the concussion has more of an affect for what it's intended for.

Anybody like EMP's?

i prefer flashbangs over concussion grenades, I don't know why, I just do

I have found a love for the EMPs don't you just hate it when theres an Osprey and your Stinger goes right through? EMP boooooiiiiiii

I prefer Stun grenades and EMP.

Flashbangs suck, always when I use them I don't see any effect, but when someone uses it to me, I'll be blinded about 3 to 6 seconds which is retarded. Also the fact that it hurts to your eyes when people spam them and that the blast shield pro's resistance is really crappy doesn't give me anything positive to say about them.

I hate that in every god damn shooter, there is flashbang as tactical grenade.

Portable radar, I guess I'm the only one who doesn't like it, I hate how sometimes when I play the whole enemy team is using that thing, then again it rarely bothers me even though I don't use assasin.
