I've actually had a lot of fun with synthweaving so far. But then again, I'm leveling with a friend who's gone Knight and Artifice and we share gear back and forth. Want to know who's been making the greater amount of gear? Me. I frequently craft new blues and green items every level, had decent success with the reverse engineer to make some gear which usually blows anything I get on that planet out of the water (to be fair though, I am a few levels ahead of the leveling curve). I make a set of green gear, then make it again and RE it for a chance to get a blue schematic to help me level my crafting skill even more while improving my gear, and I've been doing pretty well with credits (had over 70k before buying my speeder and skills.
All this armor means I can select commendations rather than going for a green upgrade, which means I can purchase mods and equipment from that planet's level (shame that resolve mods seem a bit rarer). Which keeps the Jedi robes, double bladed lightsaber, and social pants from coruscant leveled (and thank god, because I'm NEVER wearing a dress). I've had multiple critical successes too, it's just a shame I can't craft any augments yet for those.
Oh yes, I've also discovered schematics to make modable jedi robes for Consulars and Jedi Knights, which I could probably start selling on the market for some decent credits if I wanted to be bothered.
