Yeah, I would never do a 100 crystal refresh for regular energy. I did 3 of the 50s for a few months while I finished baze and Nihlus etc, but now don’t have many left to finish, so I usually only do 1 of the 50 refreshes to make sure my tickets get there, and save the rest for gear in shipments.
The 1400 Raid gear ones that you’re talking about are a good value compared to getting them other places. Holoprojectors and eyeballs are the other things I buy regularly cuz they have a great value.
Definitely worth it to speed up the gearing process, unless you’re hoarding for a future release ....
