unless maybe they make new schematics for higher level resuables once the expansion is out?
They've already said reusables were a misstep and won't be continuing. Rakata won't be removed but they'll slowly become obsolete.
As for artifice, combine it with cybertech on another toon and you can neatly recycle your old gear as you get better. The recycled mats can be used to gear up faster. Dedicated raiding guild or not that's a great advantage.
Similarly you can RE WH gear from pvp'ing and black hole gear from comms to make extra credits.
None of this involves NiM raiding and everyone can do it.
