So I had an idea, and it's probably something that anyone with rare crystals will think is terrible, but suck it up For Jedi/Sith a color crystal is as much about your visual customization as it is about the stats in my opinion. When in combat or flourishing your weapon it is an immediately visible aspect of your character. Personally I want a white crystal, just white, not white/black, not blue/purple/white, or any of those other ridiculous double or triple color combos. Just white. Which means I would have to know when Cartel Pack 1 is on sale again AND drops loads on packs that likely have everything BUT the crystal I want...or drop between 4 and 8 million credits on the GTN. But I think there is a solution....
There are so many different crystal color options now why not create a crystal pack? Like the dye module it can come with two random crystals from any of the Cartel Packs released to date, price it at say 350 since the purchasable crystal is 500 and the dye module is 200. It does have stats, so higher than a dye, but it's random so if you don't PvP then purchasing 5 packs and getting all PvP crystals is about as uselessly frustrating as it can get. Just a thought. Really wish there was a valid place to put suggestions so someone in development might see this idea, but... *shrug* Just a thought.
