One of the best ways to prevent people from killing you is to stop them from knowing where you are.  The Perks required for a completely invisible class are:

• Blind Eye
• Assassin
• Dead Silence

The most important Perk here is Assassin, it hides you from UAVs and Advanced UAVs and does the most to prevent enemies from knowing where you are. In a game type like Domination it is very easy to obtain a UAV, especially if people are using Support Streaks, and if you are struggling in a game, your life will be made a whole lot easier by throwing Assassin on the Perk 2 slot.

Blind Eye and Dead Silence are less necessary, Blind Eye is only required if the enemy team has Air Support.  In my opinion a good starter class would be as follows:

• M4A1 Silenced
• FMG9 Akimbo
• Semtex
• Flashbang
• Sleight of Hand
• Assassin
• Stalker

Using this class will allow you to keep your position hidden from all enemies, with the addition of a Silencer on your gun meaning that you will never be marked on the map, even when firing.  With your position hidden, you can kill opposing players before they know where you are - if the enemy doesn’t know where you are he can’t defend himself.

Using the same class with Blind Eye in place of Sleight of Hand will allow you to avoid being killed by attack helicopters and other lethal kill streaks.  Dead Silence is an option over Stalker if you want to ensure that people can’t hear you coming, however this is not often very important.

Something to note is that some people seem not to use the Assassin Perk out of pride, however if you are finishing with more deaths than kills in most games my feeling is that avoiding appearance on the enemy mini-map is more important than being able to say, ‘I don’t use Assassin’.
