That's a very specific case though:
1) You have to be armormech as they are bind on pickup
2) Belt and Bracer are the only slots that are REALLY hard to find in custom and so you can't slot them with the daily commendation mods, armoring and stuff
3) Those recipe still require Biometric Alloy which drop in Hard Flashpoint
So besides that EXACT exception you mentionned, everything you can get from daily commendation is better than crafting. You can get Purple 50 Armoring, Enhancement, Mods, Barrels and Hilt, that are all better than the crafted (they are only 49)
Same for the Ears and Implants that you can also buy with dailies. So yes, Belt and Bracer are the only slot that are good while crafted.
Yes the itemization is a bit ****ed right now, especially raid wise.
The worst thing certainly being that everyone will look the same, they said "Yeah but you have the custom gear and mods for that!" but you can't remove hilt, barrel and armoring from raids gear, so you are stuck with it if you want best armor/damage.
Which means that in 6 month everyone will look exactly the same in full columni/rakata gear.
We need proper itemization and we need proper appearance slots.
