I don't like standing still when being shot at, I like to strafe.  So it's suppose to be harder to shoot at the person.  You have 3 placement explosives that it doesn't trip.  IMS, claymore, and bouncing betty, no delayed explosives means deaths everywhere. All we had in MW2 was claymore, so this is a lot compared to MW2. 

People that don't use sit rep, can use the sounds of the placement explosives to hear someone coming.  I like running through them quick and kill them before they have a chance to turn around.

Is the placement of the perks in tiers messed up in this game?  Yes.  But stalker is by no means cheap.

I use stalker all the time, it's good when you come across snipers who try to quick scope you, iv taken out a lot of snipers trying to do that shite on me

Dealing with someone running around the map with stalker is a lot better than dealing with someone sitting in a corner with stalker.

And how did commando ruin the game anyway? That stuff was fun, and I never minded other people shanking me from across the map because I could do it just as well, since there wan't any lag comp back in the good old days.

Was sarcasm, except for the lag comp part. I miss that about the CoD4 days.
