Same here. Juju is sitting in the vault, waiting for some sort of buff. I have it almost maxed out. Just need last ascendant damage upgrade. I hope it wasn't a waste of time getting it, and all the time it took to upgrade it.

Thorn is decent if you are an avid Handcannon user who likes it. If you don't, it's a bad gun indeed. It really just needs more rounds or reload speed. It can pierce enemies already, so I don't see what else it could use.
