Ok i'll feed the troll..
Grade 5 lockboxes pre-nerf = 1000-2200 credits per mission and mission times 22-40+minutes, the "profit" was roughly 400-1200 credits per run (don't forget, it takes up to 40+ minutes at this grade level) which i make in pure credit drops in less than 5-10 minutes of killing mobs.
Grade 5 lockboxes post-nerf = 1000-2200 creds per mission, same times, 22-40+ minutes and the boxes return roughly 400-1200 credits, thats a minimun loss of 600 credits and minimun of 22 minutes.
I bet the whiners are happy now, don't cry when crafting-mission and augment prices skyrocket with minimum of 700% net.
You got your nerf, now live with it.
