Your goal should be 750 crystals a day in spending.
Simming for Gear is almost always going to be cheaper than buying it in the stores or packs.
If you can't afford the full 750 a day then focus what is on "Guild Dailies" special.
I always do what is on special, always, and the full 750 is on Dailies for Late Tuesday & Early Wednesday.
Gold (Regular) energy is on special every day of the week but Sunday.
Red is 4 days a week Sunday-Wednesday
Blue (Fleet) is 3x a week (Tuesday-Thursday)
Mod is only 2 days a week w/ All Energy.
Get the above started & then after that focus on what your pushing for (Cantina/Relics, Fleet/G12, Mods/Mod, Shards-Gear/Regular.
Some extra Red - Gold is always good on Thursday/Friday & Sunday to hit your 600 tickets.
Once you can support 750 a day, then hoard for packs that cost crystals that are good deals.
(690 for Kyros, 1599 for Relics, are both decent buys)
