Hey Guys!!

I know how to xp farm and level faster! this is just in-case you didn't know this

Warning : this does take some time depending on the server

step 1 : battle log
step 2 : browse for servers
Step 3 : make sure nothing is ticked in "SEARCH FOR SERVERS" except ALL THE REGIONS!
Step 4 : Where it says Filter by server name type "NO KILLS"
Step 5 : you should see a few servers join one with 8 or more if you can doesn't matter that much
Step 6 : when in the server get in a heli or be a passenger (preferably your squads) any type and what you do is capture all the flags! your team capture some the enemy team captures some and you keep doing it in a loop sort of thing you take theirs they take yours and so on.. -- Remember do not kill enemies! (you will get kicked/banned from the server) just capture flags ! --
step 7 : Keep doing it all game or for how long you want to and EARN THAT XP YUM

This will rank your class up what ever one your using e.g engineer, assault, plus your heli! i done it for about 1hr with a squad and got 74k xp in game and all together about 150k with service stars and stuff

Enjoy
