I actually feel like the stun/flash grenades are weaker in MW3, people are always fighting though the stun.

I feel that stuns and flashes are the only things in the CoD franchise give an advantage to rushers and absolutely no advantage to campers.

What I don't feel is fair is that it takes the same amount of time to throw the flash bangs as it does the concussions. They should have made it like they have in the previous ones where it is quicker to throw the concussions than the flash bangs for obvious reasons.

Let's nerf everything!!!  That is the theme for these forums.  I 100% agree with ghamorra, the size of these maps makes it seem like they are over used and on some maps people really do abuse them. 

Myself included, I only do this right after I prestige.  But for level 1-20 I will play Drop zone.  Put on RECON and BLAST SHIELD, and flash/stun/nade the **** out of people.  Last night I had 32 assists on one game.  I always end up getting BLAST SHIELD PRO after 2 or 3 matches and after about 5-6 matches I've got RECON PRO and almost maxed out BLAST SHIELD. 

It was hilarious b/c I just reached 7th prestige, completely forgot to go and play DROP, and I get to level 5 and I'm like WTF, why is it taking so long to level up to 20?  I remember about good old DROP, in one match I went from level 5 to level 12.  Next match from 12-15.  I think it only took 4 matches to get me to level 20, where SPECIALIST is unlocked.  Then I went back to my beloved HC KC.  For me that is the easiest way to go from 0-20 in like 5 matches.  I love it. 

Disagree with OP, and totally with ghamorra Flashes etc are fine... leave the game alone.. DOWN with NERF'ing

I agree with ghamorra. It's not the stuns, grenades, etc., it's the maps. There's a spot on hardhat, where I'm guranteed to get at least one kill from my grenade, and I'll likely recon the whole enemy team, even if I did only start with one flash.
