Shipment Question for the community
I started playing SWGOH a little over 2 years and I have made some great progress thanks to this community. I have been hoarding certain shipment resources like Cantina and Galactic war because I have acquired all of the shards. I assumed, it is an industry wide standard for something like this to be on a rotation or updated but I am starting to think my assumption is probably wrong. So, if the community can help me out one more time and answer my question it would be greatly appreciated.
Are these shipments updated annual, biannual, or never?
If never, is it productive to just use these currencies are as a Shard Shop farm?
Is there a better use of these currencies?
Are there any rare, once a year events, that offer valuable resources for these currencies that I am unaware of? For example, on X Day, you can exchange 50k Galactic War currency for 1 zeta.
Thanks in advance for anyone who takes time out of their day to reply.
