Yes they are as rare as you think but there extremely easy to get how to make it easy Remember that day you downloaded this game and finished the tutorial after that you did a job most likely that first job it can give so many Ec if you do it over and over again for day one to lcbc Unload and see later for proof
If you redo ANY job, you have a chance at ec. But it's rare, and from what I've noticed is that the larger your stats (After about 300kcs) the more unlikely it is for you to get ec. I get more ec drops on an alt around 100kcs than I do on my T6lc main.
Most of us knew this already. But I still see people asking how to get ec. The first job does drop the most. I have 5 accounts, all different kcs ranges. I get about 1 ec from every 1 1/2-2 unloads. I'm pretty sure there's a guide that goes into more detail. I think you have a 1/50 chance of getting a ec per successfully completed job. So it does mean you can get 2 or more ec's on an unload, I've seen it happen on all my accts.
And ik it is already known just people are still asking for help and how to get it but this is the advanced shortened forum for it just for the people that hate reading a lot even if that is still "so much"
