(adsbygoogle = window.adsbygoogle || []).push({}); I've been doing this for a long time now.
Every time I prestige I'm leveling up till level 40 for the stinger.
Turn on the double XP and use the specialist point streak.
Choose only 1 perk and use hardline.
So after 3 kills u will get the specialist bonus (+500 a kill) and on top of that the double XP.
So for a normal kill you'll get 2000 xp. If u plant a bomb 3000xp etc.
If the enemy calls in a uav you'll pull out your stinger.
You'll earn 1000xp for a uav, 6000 xp for a carepackage chopper and 4000xp for a normal chopper I believe.
This way you'll earn 20k-40k a match easily.

NOTE THIS IS FOR SEARCH & DESTROY!
It's always best to spend your double xp time in S& cause in domination you'll lose 9 minutes and in search you'll lose like 5, because it counts the time your alive.
Hope this helped. Tell me if I forgot something.

Gonna do this right now (y)

forgot to say its in search.

Looks great, will definitely be using this when I get my next token (probably in a few hours).

Cheers.

yeah this awesome, was lvl 20, now 50 after 1 hour!!!!

Been doing this for 2 prestiges..

thaaanks ,,

hardcore kill confirmed is better plus 1 perk specialist doesn't do shit.

Because if you use 3 it takes longer to get the Specialist pro thing, while with 1 you get 3 kills and you have every perk, its just quicker, plus after 3 kills you get the specialist bonus

Yes Hardline standard, then any 2nd perk can be used, cause at 3 kills you get every perk anyway
