My casual style is such:
I start with Black Hole, CZ, and Oricon dailies for a quick 1500+ Cxp, then run veteran Black Talon(not at all difficult) for 850ish CXP in about 15 minutes. If it is bonus for warzones or I still need to complete the weekly I will do some PvP, but it isn't as consistent as running BT since I am pretty newly back to the game and haven't found a guild to run with.
I hear people don't like running alts with this system, but I've been running my 2 level 70s to increase chances for schematics/mods to RE. A nice bonus out of BT are the 2 refined isotope stabilizers that drop per run. I have alts with all the crafting professions at 600 so these are handy to generate a ton of revenue for me crafting 230 hilts, barrels, and armorings. With prices on Harbringer such as they are I am easily making over $500k profit every BT run which is really helping given the massive inflation since I last played full time in 2014.
Both my characters are at 3/6 for set bonuses(Command rank 45 and 30) so the RNG hasn't been too bad to me so far, but I've had my fair share of bad RNG luck over the past 15 years of MMO gaming.
With all that said BW don't take this as an endorsement of your current endgame, its not. GC would be fine as a supplement to a comprehensive loot system, but as the end all be all it is lacking quite a bit.
