Dead Silence.

assasin

Haven't played the game yet... keeping an open mind.

There is no "best perk" because they all serve a purpose.

-SoH's faster reload & weapon swap can mean the difference between dying & getting the kill.

-Recon helps the team by marking targets when you take away an enemy's health.

-Blind Eye allows you to safely take out enemy air support

-Quickdraw's faster ADS can often mean the difference between dying & getting the kill.

-Hardline Pro turns 2 assists into a point towards your next PSR.

-Blast Shield saves you from explosive damage & stun/flash spam.

-Assassin allows you to flank and play the anit-camper.

-Sitreps gives you better awareness; much better awareness.

-Dead Silence lets you creep around the map.

Unlike Blops, MW3 seems to have A LOT more counters for things -- even the almighty BEADS kit is countered by Advanced UAVs, Recon Drones & the Recon Perk. I really don't see MW3 being dominated by any one perk like Blops was.

Well it depends on the type of player. Blast shield will be the best for objective players in objective modes. I think Assasin is the obvious winner for Team deathmatch/free for all players. Scavenger will be very important for your "slayers" that go on extremely long killstreaks. Hardline will be the best  for the players that aren't able to pull of those long killstreaks. So in my opinion you can't say just one perk is the definitive best perk out of the bunch.

We don't know because the game isn't even ******* out yet.

As in black ops dominating perks being light weight , slight of hand , ninja I'll bet money that mw3 is gunna be slight of hand quick draw and dead silence

Lol on an Overall level in usefulness. Its Assassin/Ghost without a doubt, cuz all Mediocre players do is abuse the radar.

for me assassin pro is the most essential but i think the BEST perk is recon pro because coupled with a smg and hardline pro it racks up the kills.

especially since i run support most of the time.  gets me to the dreaded EMP faster.

sitrep pro is the most powerful perk in cod history. It's a legal wallhack
