Grinding fast in Eureka

[BillyKaplan]

I was told that it took up to 3 hours to get a drop, I'm not interested in grinding for that long solo.

You're going to wait longer for a change they're likely not going to make until they nerf the thing if at all. You also don't have to do that solo, you can get other lowbies you level to help, maybe while working on a low level NM. There ARE low level trains going choo choo.
