All that being said, I'm finding the process to be really slow and painful. I'm generally just running veteran flashpoints for gear and that seems to work okay. Sometimes I'll get lucky and get 2-4 upgrades on a flashpoint, but sometimes I'll get nothing at all. Just RNG.
My Jedi Guardian is sitting around gear level 290, so he's got quite a way to go to that magic 306.
I've also been working on leveling up my crew skills across all of my characters.
The above table is what that looks like at the moment. I'm probably going to switch one of Ganntt's skills to Diplomacy or Investigation, but I still need to figure out how much either of those may be critical to leveling some of crafting skills.
That's about it for now.
