What they need to do is put new crafting materials in the first part of CT, it seems to of done well for The first coil of bahamut, people are always running T4 for allagan silk, wootz and leather. Stick some of that on every CT boss drop and people will start doing it.

For now though I assume it will almost be impossible to get anyone willing to do it, except for maybe ninja's that want FUMA gear.
