Mangoose: Yeah, that'll do for stats, but what people really want is customization, and I'm no different. I'd probably want some cool robes, maybe some dyes, a special crystal, a particular mount, some decorations, et cetera—just like everyone else, which, along with the awful cash shop scheme, is probably why everything cool costs hundreds of thousands or millions of credits. I'm thinking more of the 18k x 4 credits per heroic (plus whatever else you get from the mission) and so on. Granted, I really haven't played the game for that long, and a lot of this is standard theme park MMO stuff: figuring out which crafting materials and/or crafted items sell briskly for a good price, which missions/mobs to grind, and so on.
The path of least resistance, and not by coincidence, seems to be to pay $40 and buy those 30x hypercrates to open and sell. The coolest shit seems to come from the Cartel shop (and some exclusive rewards, like "PvP season 1 mounts" or whatever), and isn't looted or crafted, which skews the economy in some fairly obvious ways.
Side note: At one point, my custom outfit vanished/reset for no reason and I had to pay ~6,000 credits to set it up again. That's a really obnoxious currency sink, but I needed to cover up the low-level Consular
rags robe.
