Disclaimer: The following calculations were made with the following remark; that the experience to earn 1 cert point was 500. But this may have changed to 250 xp per cert which effectivly doubles the amount of cert points! Also if you boost experience then you can probably in theory earn like 1000 certs per hour.
The concept is very easy. You have three players where as two of them are of the same faction and the solo player is of another enemy faction. The two teammates both play as medic and the enemy guy play a engineer(for the unlimited ammo)
Here is how the method works. Engineer kills one and the other medic resses him and he kills him again and the medic ress again. When the medics are in squad then they earn 100 xp per ress and the engineer earns about 120 xp per kill.
a ress takes about 3 seconds so you should get around 20 kills per minute and in one hour you earn 240 certs. If you are two active medics then each medics earn only half of the certs in total. If you find someone who can just put a automouse clicker and just automatize his part then both earn about 240 certs per hour.
This will be alot greater for the one shooting though. He will earn gold medal on all his weapons and earn alot of certs just from that. If you got any kind of boost then you will earn RIDICOLOUS amounts of certs. All these calculations were from no boost at all.
This worked until the end of beta, haven't tested it on release yet but i see no reason at all why they would fix this.
If there is a demand then a more concluding discussion will be put up and also a video were we perform this!
Have a nice day everyone
