Lets get a thread going on classes. Post your custom classes and why you have what you have. I'll start:
Slot 1 (FOR: S&D Attacking, HC games) :
AK74U + Silencer (Powerful SMG, open sights, silenced)
USP 45 + Silencer (More powerful than 9mm, more ammo than 1911?)
Stun Grenade (n00b, shows hit indication)
Bomb Squad (used most on S&D, shows claymores/c4 placed on objectives. good for avoiding detection when placing bomb)
Stopping Power (used to up the power of the AK74, unless in HC for which UAV Jammer is used)
Dead Silence (avoid detection, allows me to hear others easier)
Slot 2 (FOR: S&D Defending, HC games) :
MP5 + Silencer (sane reasons as AK74)
Colt 45 + Silencer (same reasons as USP, but I like the colt 45)
Stun Grenade (same)
Claymore (for defending S&D objectives)
Stopping Power/UAV Jammer (depending on HC/non HC)
Dead Silence/Extreme Conditioning (dead silence for normal games, extreme conditioning to get to planted bomb quicker in S&D)
Slot 3 (FOR: medium range engagement, TDM, normal games, etc...) :
M16 + Acog (accurate, powerful, more ammo and quicker fire than equivalent sniper rifles, can be used in closer quarters)
Desert Eagle (can shoot fast, powerful, and if I'm using my pistol, it's in CQB)
Stun Grenade (always the same reason)
Bandoleer (need moar ammo!)
Stopping Power (kills faster duh)
Deep Impact (shooting concealed targets)
Slot 4 (FOR: helis, free for all, suppression)
RPD + grip (best sights, low recoil, high power)
Desert Eagle (its a DE duh)
Stun Grenade
RPG 7 x2 (for helis)
Sleight of Hand/Double Tap (faster reloading, I like to stay alive, maybe I just want to spray and pray)
Deep Impact (spraying walls, suppression)
Slot 5 (FOR: sniping, no-scope kills)
M40A3/R700 (depends on HC/non HC)
9mm + Silencer
Smoke Grenade (cover movement, distraction)
Claymore/Bandoleer (position defense or need to kill lots of people)
Stopping Power/UAV Jammer (HC vs. Non HC)
Steady Aim/Deep Impact (do I want to no-scope? or am I plain sniping?)
That's me... how bout you guys?
