I have 30 heroics I run because of the speed, easy and dont have to fight for spawns on them, I make about 1mil to 1.1mil in lil over an hour. I have 8 commandos and 2 vangaurds I run these on because of the fast dps. I save up about 130 to 140 of each alliance crate then ill run a toon through kotfe and pretty much insta rank 20 with all 4 guys. you will get about 2.5mil creds just in opening the crates and selling the legacy gear to vendor. Then lots of credits selling the tons of comp gifts you get, i sell the planet decos at 200k each. then u get mounts you can sell anywhere from 100k to 500k. These heroics are a huge cash cow and there is NO need to exploit at all. the money is so easy
