Just try out these classes and tell me what you think!

UMP45
2x Attachments Rapid Fire/Silencer
Javelin (certain maps I get at least 2+ Kills with it) Drop it once I've killed someone and pick up their gun...
Extreme Condition Pro
Assassin Pro
Dead Silence Pro
Claymore
Portable Radar/Concussion

Yeah I tried that awhile back but I usually play with a party and nobody gets a high enough killstreak to make blind eye pro count. And NGU, that class is beast! But I like the rapid fire with it because the rate of fire on the mp5 is not that high.

Sniper class: It's a lot of fun to use. Reasons for choices below.
L118A (Variable scope w/ stability) [Early unlock, feels better when scoped in w/o QuickDraw, better mobility]
MP9 (Silenced) [Quickdraw machine pistol w/ SOH, best of the machine pistols IMO, great range]
Sleight Of Hand PRO [fast reload and switch for MP9]
Assasin PRO [Stay off the map, no real need for QuickDraw bec/ I can quick-scope w/o it]
Marksman PRO [good for early kills and darker maps, great sniper perk, I use this class in other game modes as well]
Lethal: C4
Tactical: Smoke Grenade or Portable Radar [Smoke Grenade for objective playing and bomb planting. Radar for patrolling and camping]
Killstreaks: [Standard SnD killstreaks]
UAV
Care Package
Predator Missile

Overkill PRO class: another fun class for SnD and hardcore game modes
MK14 (Red Dot Sight w/ Silencer) [Fun gun for SnD, and a beast in hardcore games, Long range And medium range]
MP7 (Silencer w/ Rapid fire) [For short to medium range, great sub machine gun, low recoil)
Sleight Of Hand PRO [Combo w/ Overkill]
Overkill PRO [Master of all ranges]
Dead Silence PRO
Lethal: Frag Grenade or C4 [frags are great for tactical playing, and I like using C4]
Tactical: Smoke Grenade [Objective playing, getaway tactic, fun using it]
Killstreaks:
UAV [standard kick start, it's a must in hardcore]
Predator Missile [Tactical pred missile use, stack towards Assalt Drone]
Assault Drone [Fun Killstreak, great for hardcore, don't count on it in SnD but I really only need up to my pred for standard SnD games being that I play in parties]

These are some of my unique-ish(?) classes in general. I do use the ACR and sub machines a lot but I do go to these when I am bored and in general. Hope you like them!

I never tried the MP5 before. IS it any better than the UMP or PP?

P90 + Silencer + Steady Aim = WIN !
